Dog Antibiotics Treat Illness

Although I always recommend that you talk to a veterinarian before giving your dog antibiotics – especially medicine that has expired or was prescribed for someone else in your family.

Antibiotics for dogs can be dangerous if you give them  the wrong dose or if the antibiotics are the wrong type.

Having said that, there are some broad antibiotics that are safe for dogs, and that can help your pet begin to feel better and heal quicker.

Common Dog Antibiotics


The first, and probably best known dog antibiotic is probably Cephalexin. It’s a broad-based antibiotic for dogs that’s also used to treat humans.

Cephalexin is a penicillin type of antibiotic which means it is used for bacterial infections of the intestinal tract, bones, skin or wounds, as well as respiratory and kidney or urinary tract infections.

This antibiotic for dogs comes in gel capsules or liquid – which is usually the preferred method because it makes it easier to mix into your dog’s food or water.

Side Effects of Cephalexin on dogs: skin irritations, digestive upset and diarrhea.


You’re probably familiar with the name Amoxicillin – it’s another broad-based antibiotic in the penicillin family of dog antibiotics. It’s an antibiotic for dogs that’s usually prescribed for respiratory infections. It’s also often prescribed for gastrointestinal infections, cellulitis, abscess and many skin infections. This dog antibiotic comes in drop and pill form.

Side Effects of Amoxicillin on dogs: Side effects are rare – but when prescribing Amoxicillin for your dog, your vet will tell you to keep an eye out for extreme changes in behavior or personality. If you see this happening to your dog, call your vet at once.


Tetracycline is another antibiotic that’s used to treat both dogs and people. It’s used to treat Lyme Disease or dogs that have been diagnosed with Rocky Mountain Fever. Tetracycline does not react well with milk, dairy products or milk. (Make sure your dog doesn’t eat or drink anything with these ingredients for at least two hours before and after the treatment is given.  Tetracycline is a dog antibiotic that’s usually given in gel cap formula.

Side Effects of Tetracycline on dogs can range from simple tooth discoloration to vomiting and diarrhea all the way up to bone growth defects.


Terramycin is a dog antibiotic that is used to treat bacterial eye infections and corneal ulcers. It comes in ointment form and is rubbed on your dog’s inner eyelid so it can mix with your dog’s tears. Terramycin stops the protein bacteria feed on, which stops the infection.

Side Effects of Terramycin on dogs are mild – a little blurred vision and occasional site irritation.

Alternative Dog Antibiotics

There are other dog antibiotics of course. Natural formulas that can be made from flower essences and other happy dognaturally occurring products from nature. If an infection is already severe you may want to stick to conventional medicine before it becomes worse and learn about the alternative remedies at the sign of infection next time.

Also using preventative measures to lessen chances of infections is a good course of action. Remedies can also possibly help your dog to get  better faster.  If your dog is sick, doesn’t  look right  get your dog to a vet and talk about treatment possible dog antibiotics or other protocols to  help your dog get back to his happy healthy self.
