Antibiotics for Dogs: Everything You Need to Know

Are you at home with an unwell dog and are wondering if “antibiotics” can help your furry friend? Read on to find everything including types, benefits, and negative effects of Antibiotics for Dogs in this informative article.

Dogs and cats, like humans, suffer bacterial illnesses that necessitate antibiotic therapy. Antibacterial drugs are necessary for treating these infections since they kill the contaminated organism while leaving the healthy cells of your pet unharmed.

Some antibiotics operate by preventing bacteria from forming cell walls, preventing them from reproducing, while others starve bacteria, preventing the afflicted organism from converting glucose into energy.

An Antibiotics are one of the most commonly recommended treatments for dogs, and they are used to treating bacterial infections. Infections can affect the skin, mouth, eyes, ears, urinary tract, lungs, and other organs.

Antibiotics come in a variety of shapes and sizes, as well as distinct classes. Each class fights microorganisms differently.

Most Recommended Antibiotics for Dogs

Veterinarians most commonly prescribe the following antibiotics to dogs:

The following are the five most commonly recommended antibiotics for dogs:

Amoxicillin/Clavulanate—This antibiotic combination, which is related to Penicillin, is used to treat a wide range of bacterial diseases, including skin infections, respiratory infections, gastrointestinal infections, and genitourinary infections.

Gentamicin — is a medication used to treat eye infections, ear infections, and pneumonia in dogs. To assist minimize redness and swelling, this treatment is used with an anti-inflammatory agent.

Chloramphenicol—Chloramphenicol is an antibiotic with a pH level that allows it to flow entirely through your dog’s system. This makes it an excellent alternative for treating bacterial infections in the organs in dogs.

Sulfamethoxole — is a drug that is used to treat infections in the urinary tract in dogs. This antibiotic is harsh on a dog’s gastrointestinal tract, and it frequently causes nausea, vomiting, diarrhea, and weight loss.

Make sure your dog drinks lots of water while taking sulfamethoxole to keep her hydrated.

Tetracycline—By preventing protein synthesis, tetracycline can treat a wide range of bacterial illnesses. Tetracycline is utilized when another antibiotic has been shown to be ineffective because it has the ability to break past the bacteria’s protective barriers.

Other Recommended Antibiotics for Dogs

Apart from the above-mentioned antibiotics, there are various others that many veterinarians recommend to dog parents: 

Doxycycline — Doxycycline is an antibiotic that is used to treat a variety of infections in dogs. Tick-borne infections, leptospirosis, toxoplasmosis, and psittacosis are among them. It’s a bacteriostatic antibiotic that stops bacteria from proliferating and shuts off their protein production.

Clindamycin — Clindamycin is an antibiotic that also has antiprotozoal properties. It’s used to treat infections of the skin, bones, mouth, and respiratory tract, and it works best against gram-positive bacteria.

Clindamycin normally acts by suppressing bacterial growth, although it can also kill germs in specific cases.

Cephalexin — Cephalexin is used to treat a variety of bacterial infections, including those of the skin, urinary system, soft tissue, and respiratory tract. It’s a broad-spectrum antibiotic, like Amoxicillin, which makes it a popular choice.

It is, nevertheless, extremely beneficial in the treatment of deep skin infections. It can kill a wide spectrum of bacteria, both gram-positive and gram-negative, by causing the cell walls to break down and become susceptible.

Metronidazole

Metronidazole is an antibiotic that also works as an antiprotozoal. It’s one of the most potent medications on the market, and it’s used to treat a wide range of conditions, including: 

  • — IBD 
  • — Giardia 
  • — Oral infections 
  • — Diarrhea problems 
  • — Periodontal disease

It can enter bone and is extremely efficient against bacteria that can thrive without oxygen (anaerobic diseases). Its anti-inflammatory characteristics make it an excellent treatment for gastrointestinal infections and diarrhea caused by certain disorders.

Antibiotics are used to treat a variety of infections.

What Are the Functions of Antibiotics for Dogs?

Antibiotics are classified as either bacteriostatic or bactericidal. Depending on the type of condition, each is used.

Antibiotics that are bacteriostatic inhibit bacteria from growing and reproducing. This offers the host’s body enough time to use its natural immune system defenses to fight off the illness.

Antibiotics that are bactericidal kill bacteria completely. Both types of antibiotics operate to protect people from a variety of bacterial diseases, and they can be taken as tablets, capsules, liquids, or topical ointments.

Antibiotics can be used to treat wound infections, urinary tract infections, respiratory infections, pneumonia, ear infections, skin infections, gastrointestinal problems, and soft tissue, bone, and dental infections in dogs.

When Is It Appropriate to Take Antibiotics?

When bacteria is the source of the infection, rather than a virus that cannot be treated with medicines, antibiotics should be used.

Only your veterinarian will be able to pinpoint the source of the infection and provide the appropriate medication.

Can my dog have an allergic reaction to the Antibiotic prescribed?

Yes, Antibiotics can cause allergic responses in dogs, but this is a rare occurrence.

Dogs, like people, can develop drug allergies at any moment, therefore past tolerance of a specific antibiotic does not guarantee that it will not produce an allergic reaction in the future.

Allergic responses can range from mild to severe, and they can happen right after you take the antibiotic (anaphylaxis) or later. Dogs may exhibit one or more of the following symptoms during an allergic reaction:

  • Difficulty breathing 
  • Seizures 
  • Excessive salivation 
  • Vomiting 
  • Diarrhea 
  • Swelling of the face or muzzle 
  • Skin rash or hives 
  • Difficulty breathing

If your dog is having problems breathing or has facial swelling, you should take them to the nearest open veterinary practice as soon as possible. Notify your veterinarian that you are on your way.

Treatment usually consists of steroid and antihistamine injections to stop the reaction, as well as supportive care as needed (oxygen therapy, fluids, etc.).

If the reaction is moderate, meaning your dog is breathing normally, but you observe additional symptoms, you should get medical assistance from your veterinarian. The antihistamine diphenhydramine (Benadryl) at a dose of 1 mg/lb may be recommended.

Side Effects to Antibiotics in Dogs

Antibiotics can be quite helpful in resolving the problem and returning your pet to a happy and healthy state. Antibiotics do not all have the same adverse effects, Fortunately, most antibiotics are generally safe for dogs and only have minor side effects.

However, antibiotics are not without their drawbacks, and they can sometimes cause harm to your pet. The following are some of the most prevalent antibiotic adverse effects in dogs.

  • Gastrointestinal Disturbance

Nausea, vomiting, diarrhea, and a loss of appetite are side effects of some antibiotics. Within a day or two of starting antibiotics, you should start to notice these symptoms.

Antibiotics given with food can help some dogs avoid these issues. If your dog’s GI upset persists despite the antibiotics being given with food, get assistance from your veterinarian and request vet to switch to different antibiotics.

  1. Imbalance in the Microbiome

Antibiotics can kill beneficial bacteria in the body in addition to destroying infection-causing germs. Dogs, like humans, contain beneficial bacteria in their systems, particularly in their gastrointestinal tract and on their skin.

These bacteria play an important role in maintaining the body’s homeostasis. They improve the dog’s immune system, digestion, and even the production of important vitamins and nutrients.

Dogs may also experience GI symptoms such as diarrhea as a result of the gut imbalance. Secondary infections, such as yeast infections of the skin or ears, can also develop in dogs.

  1. Effects on the Nervous System

Antibiotics can cause ataxia, dilated pupils, head tilt to one side, nystagmus, and even seizures in some people. Metronidazole is a regularly used antibiotic that has been linked to various adverse effects.

If you observe any neurological problems in your dog, stop using antibiotics and call your veterinarian right away.

Can My Dog Have Resistance to Antibiotics?

When it comes to the usage of antibiotics, resistance is a worry in both humans and animals. It happens when germs grow resistant to the antibiotics used to kill them. 

As the bacteria multiply, the infection worsens and becomes more difficult to treat.

Antibiotic resistance is prevented by veterinarians prescribing the most appropriate antibiotic for the bacterium, selecting the appropriate dose, and advising on the optimum treatment duration.

This is why, even if your dog appears to be improving, it is critical not to complete the specified antibiotic treatment regimen and contact the vet immediately for a proper course of action.

What Effects Do Antibiotics Have on Your Pet’s Gut?

The gut microbiome refers to the bacteria and other germs that live in your pet’s digestive system (gut). When your pet has an infection, your veterinarian (DVM) may prescribe an antibiotic to help treat the infection.

Unfortunately, oral antibiotics can’t tell the difference between “bad” bacteria that cause bacterial infections and “good” bacteria that help your pet stay healthy, so they kill both good and bad bacteria.

This may cause a continuing imbalance in the intestines in some cats and dogs, which may lead to health problems such as persistent diarrhea, vomiting, or constipation.

How to Care for Your Pet During Antibiotic Treatment?

Antibiotics, despite their bad side effects (such as diarrhea), can be an important tool in helping your pet fight deadly diseases. Fortunately, there are certain things you can do to help your dog during and after antibiotic therapy to help them get better.

  • S boulardii, a yeast-based probiotic

Saccharomyces boulardii, or S boulardii for short, is a unique probiotic that differs from most others in that it is a yeast strain rather than a bacteria strain.

S boulardii, unlike many bacterial probiotics, is exceptionally resistant to drugs: yeasts are unaffected by antibiotics, thus a yeast-based probiotic like S boulardii is nevertheless highly helpful for pets who need antibiotic treatment.

Furthermore, S boulardii easily pass through stomach acid, arriving in the intestines whole and alive, whereas many bacterial probiotics immediately perish when exposed to stomach acid.

Antibiotics destroy many bacterial probiotics because they can’t tell the difference between good and bad bacteria.

Antibiotics have no effect on S boulardii because it is yeast. In fact, studies have indicated that administering S boulardii along with an antibiotic reduces the likelihood of pets developing diarrhea during or after the antibiotic treatment.

  1. Encourage a Healthy Appetite

Antibiotics can cause lethargy, nausea, and/or lack of appetite in many dogs, making them less likely to eat their food. It is critical, however, that your dog continues to eat since their bodies require energy to fight illness and repair damaged cells. 

If your pet refuses to eat, do not force them to; instead, wait a few hours and try again.

If they refuse to eat it, consider adding something to it to make it more appealing. The use of low-sodium beef, chicken, or bone broth is frequently beneficial.

How to Care for Your Pet After Antibiotic Treatment?

Let’s talk about what you can do to support your pet once you’ve given him or her antibiotics:

  1. Add a Prebiotic Supplement

Antibiotics aren’t selective about which bacteria they kill: they may kill bacterial diseases, but they also kill a lot of good bacteria in your pet’s stomach, which helps them battle inflammation, reduce cancer risk, and maintain a healthy weight.

A prebiotic supplement, such as psyllium husk powder or inulin, can assist support the growth of these beneficial bacteria by acting as a food supply.

  1. Examine your gut microbiome

Individual pets can react to the same antibiotic in completely different ways. 

Obtaining a picture of the proportions and specific bacteria present in your pet’s gut (post-antibiotic) can provide greater insight into how to best maintain your pet’s unique gut depending on the bacteria present.

What kinds of Antibiotics Can Dogs Take?

Infection in or on your pet’s body can be caused by four different types of bacteria. Bacteria, viruses, fungus, and protozoa are among these microscopic organisms. 

After making a diagnosis and determining what sort of organism is causing the condition, your veterinarian will decide what type of pet antibiotic medication to administer.

The type of pet antibiotic you should use depends on the organism you’re fighting and how the drug works in your pet’s system.

What kinds of Antibiotics Can Dogs Take for Infections caused by Bacteria?

Bacteria can enter your pet’s body through a variety of routes, including open wounds, food, and simply living in the same environment as your pet. 

They come in a variety of forms and sizes, and your veterinarian will use these physical traits to determine which germs are affecting your animal.

These tiny, one-celled organisms can multiply uncheck in your pet’s body without the involvement of antibiotics, causing gastroenteritis, pneumonia, skin infections, urinary system difficulties, and a variety of other ailments.

What is the mechanism of action of antibacterials?

Bacterial antibiotics operate by destroying the infected cells while leaving the healthy cells in your pet unharmed. An antibiotic may impair the bacterium’s capacity to build cell walls, preventing it from reproducing, depending on the medicine.

An antibiotic can also starve a bacterium by preventing it from converting glucose into energy, which is a crucial function of all living cells.

Bacterial Antibiotics for pets include: 

  • Enrofloxacin (Baytril) — for infections of the respiratory, cutaneous, and urinary tract
  • Clavulanic acid/amoxicillin (Clavamox) — for wounds, respiratory infections, and skin illnesses
  • Metronidazole (Flagyl) — stomach problems, periodontal disease
  • Clindamycin (Antirobe) — bacterial infections, soft tissue infections, bone infections, and dental diseases

What kinds of Antibiotics Can Dogs Take for Infections caused by Viruses?

Viruses are the organisms that cause canine distemper, canine parvovirus, feline herpes, and feline calici virus, among other diseases that can make your pet very sick. 

These parasites can only multiply inside the live cells of other species, and they are so little that they are thought to be one-hundredth the size of a bacterium.

What is the mechanism of action of antivirals?

Antiviral medications are unable to eradicate the infection. Instead, they function by preventing the viral infection from growing and reproducing, leading it to die on its own.

While antiviral medications aren’t commonly used in veterinary medicine, most veterinarians prefer to treat all secondary bacterial illnesses that can emerge as a result of a viral infection in order to keep your pet happy until the virus has left the animal’s system.

  • Acyclovir (Zovirax) — certain herpes virus infections can be treated with this antiviral medicine for pets.

What kinds of Antibiotics Can Dogs Take for Infections with Fungi?

If your pet has experienced ringworm, skin or ear yeast infections, or the more serious and lethal blastomycosis, you know he or she has been infected with a fungus.

Fungi are microorganisms that are related to yeasts, molds, and the more common mushroom.

They survive by swallowing your pet’s cell-building ingredients, damaging new tissue, and feasting on the waste products of dead cells.

What is the mechanism of action of antifungals?

The majority of antifungal pet medicines work by destroying the fungus’ cell walls, allowing the parasite to die and the surrounding tissue to regenerate.

Antifungal antibiotics commonly used in pets include: 

  • Griseofulvin (Fulvicin) — ringworm infections
  • Ketoconazole (Nizoral) — Cushing’s disease, internal and exterior fungal infections
  • Fluconazole (Diflucan) — infections of the skin, yeast, and ringworm
  • Amphotericin B (Fungizone) — illnesses such as histoplasmosis and blastomycosis

What kinds of Antibiotics Can Dogs Take for Infections caused by Protozoa?

Protozoa are microscopic organisms that feed on nutrients in your pet’s body by either completely consuming the food generated by the digestive system or sweeping it into their “mouth holes.”

Protozoa migrate about your pet’s cellular structures, covered in hair-like structures called “cilia,” in order to gain as many nutrients as possible in order to reproduce. These small parasites are responsible for significant gastrointestinal ailments like Coccidiosis and Giardiasis, as well as the potentially fatal blood disease Haemobartonellosis.

What are anti-protozoals, and how do they work?

Some anti-protozoal pet medications act by disrupting the microorganisms’ DNA and preventing cell growth and reproduction, causing the infection to resolve as the protozoa die off.

Other pet treatments only destroy the protozoa.

Is it Possible for Infections to Self-Resolve?

Yes, your dog’s immune system can fight off some small bacterial illnesses without the need for medications.

Even if this is possible, if you suspect your dog has a bacterial infection, you should visit a veterinarian. They’ll be able to tell how serious the illness is and whether drugs will be required.
