7 Antibiotics Often Used To Treat Infections In Dogs

It is quite common for dogs to suffer from bacterial infections and diseases. For common bacterial illnesses, the treatment usually involves bacteriostatic antibiotics or bactericidal antibiotics depending on the condition. The bacteriostatic antibiotics inhibit the growth of bacteria to multiply through prevention, while the bactericidal antibiotics kill the bacteria. These antibiotics are available in capsules, chewable tablets, ointments and liquids, and it is important for you as a dog owner to be informed about these antibiotics and how they can affect your pet.

Learning More About Antibiotics For Dogs

While over the counter antibiotics are usually safe on dogs, it is still best that a sick dog is seen by a vet to determine the best treatment to be given because each dog is different and every health condition is also different. Dogs can develop allergic reactions to antibiotics so caution is always needed especially to avoid overdose.

1. Amoxicillin And Cephalexin

These are common antibiotics used for bacteria related illnesses and are related to penicillin. Amoxicillin is used to treat the gastrointestinal, respiratory and genitourinary systems of dogs, as well as skin infections. The typical dosage for amoxicillin is 10mg for every pound of body weight for every 8 to 12 hours. Cephalexin is used to treat various infections, but it is primarily used to treat wound, skin and bone infections. The dosage for cephalexin is 10mg to 15mg per every pound of body weight for every 8 to 12 hours. However, due to the possible effects of cephalexin, prescription from a vet is necessary.

2. Sulfamethox

This antibiotic is strictly used for various infections as well as urinary tract infections in dogs. However, it is important that plenty of water is drunk when this is taken and side effects include nausea, loss of appetite, vomiting and diarrhea.

3. Gentamicin

Pneumonia, ear infections and eye infections can be treated with this antibiotic alone or with a combination of anti-inflammatory medication. This is available in tablets as well as a topical spray.

4. Chloramphenicol

This antibiotic contains a certain level of pH that can go through a dog’s body completely to treat bacteria and parasite infections. It can also enter the organs of a dog to battle infections making it a popular antibiotic.

5. Sulfadimethoxine

Also known as sulfa drugs, this antibiotic is specifically used to treat parasitic infections that cause gastrointestinal conditions in dogs.

6. Tetracycline

Protection against a variety of bacterial infections can be derived from tetracycline as it does not allow proteins to synthesize. However, infections are easily treated with this antibiotic because it has the ability to break through barriers that hinder treatments of infections.

7. Doxycycline

This is similar to tetracycline and it is also used in a variety of infections to prevent growth and production.

Allergic Reactions To Antibiotics

Allergic reactions can occur and depend on the type of antibiotic taken, as well as its dosage. Most of the time, the symptoms of allergic reactions occur within 24 hours, but they often last for a few hours after treatment is sought. The common reactions include breathing difficulty, painful rashes, itchiness, coughing, nausea, unable to eat and swelling. In severe cases of allergic reactions, dogs can experience anaphylactic shock which requires immediate medical attention.

  2. Curious

    Is the amount listed for Keflex correct? Doesn’t seem right that a 140lb dog would be taking 1400 to 2100mg twice daily. That sounds like it would kill the animal. I know dogs are different that humans but 500mg twice daily is a high dose for humans and the amount listed for dogs is 4 times that.

  3. Serina Samples

    I would research weither or not there is a max dosage. This question is a month old and I would be very curious to know what the answer turned out to be.
