Amoxicillin is a semi-synthetic penicillin. It usually takes the form of amoxicillin trihydrate in medicine form. It is part of the penicillin family of antibiotics. Also in this drug family are ampicillin, nafcillin, and penicillin.

Amoxicillin works by disrupting the formation of bacterial cell walls. Therefore, it can kill both existing bacteria and prevent the growth or formation of new bacteria. Amoxicillin is not effective against viral or parasitic infections.

Amoxicillin Uses: Which Pups Need These Antibiotics for Dogs

As much as we try and keep our furry friends in tip-top condition, sometimes bad things happen. They get sick too. Fortunately, we have some great medications that we can turn to to help treat our beloved pets when illness strikes!

Amoxicillin treats infections caused by bacteria. It can treat ear infections (otitis media), bladder infections, and urinary tract infections (UTIs). It is also effective against skin infections, dental infections, and upper respiratory tract infections.

Amoxicillin Interactions: Which Doggos Should Not Take These Meds

  • Dogs that are allergic to other penicillin-related drugs should not take these medications. Animals with a known penicillin-allergy should also not take amoxicillin.
  • If your pet has shown a sensitivity to cephalosporins (such as doxycycline), it is best to avoid amoxicillin medications. Amoxicillin can interact with probenecid and allopurinol (both used to treat gout and/or kidney stones).
  • It can also interact with other antimicrobial drugs such as erythromycin, chloramphenicol, sulfonamides, tetracyclines, and macrolides.
  • Animals that have a history of allergy or asthma might not be able to take amoxicillin.
  • There are no known food interactions with amoxicillin. Also, amoxicillin is not sensitive to gastric juices. It can, therefore, be given with or without food.

Amoxicillin Dosage for Dogs

Firstly, the dosage of amoxicillin in cats and dogs is usually calculated at 5-10 mg per pound of body weight every 12 – 24 hours. For example, a 55-pound pooch will receive approximately 500 mg amoxicillin once a day.

Administer oral amoxicillin by wrapping the tablet or capsule up in a nice doggie treat. Place the treat as far back in the mouth of your pet as you can. Luckily, products like pill pockets, make giving your doggo their treats is super easy!

Antibiotic resistance is an ever-increasing problem in both veterinary medicine and human health care. Be sure to complete the whole course of dog antibiotics. This is to avoid the risk of your hound’s infection becoming drug resistant. If the bacteria become antibiotic-resistant, they can spread their infection to other parts of the body and cause much damage.
