Please Note: Many medications commonly found in household medicine cabinets can be
used as temporary remedies for minor ailments in dogs and cats. Some, though, can
produce serious, even fatal, side-
1. Aspirin
Therapeutic dose: 10mg per pound body weight per 24 hours, usually divided into two doses 12 hours apart
Example: 10 lb dog gets no more than 100 mg total within 24 hours, 50 mg AM and 50 mg PM
Maintenance dose: ½ ,or less, of therapeutic dose once or twice daily for arthritis
Adverse reactions: Stomach and intestinal irritation, ulceration, vomiting, loss of appetite, bleeding.
Discontinue 5 to 7 days before anticipated surgery or dental procedures.
Commonly used as a musculoskeletal anti inflammatory/ pain reliever in DOGS ONLY. Cats metabolize the drug so slowly as to make it, at best, ineffective and, at worst, toxic. The best uses are for muscle, bone or joint pain associated with over exertion, and for arthritis. Do not use in the presence of gastrointestinal disease such as poor appetite, vomiting or diarrhea. Always give with food and only if the dog is eating and drinking normally. Do not combine with other medications unless approved by your veterinarian.
2. Tylenol (Acetaminophen)
Therapeutic dose: 6 mg per pound body weight every 8 hours, DOGS ONLY
Adverse reactions: FATAL TOXICITY IN CATS, liver toxicity in dogs at higher doses
Commonly used as a pain reliever in place of aspirin. Do not use in dogs with known or suspected liver disease.
3. Benadryl (Diphenhydramine)
Therapeutic dose: ½ to 1 mg per pound body weight every 8 to 12 hours
Adverse reactions: Sedation, rarely excitement
Commonly used to treat allergic reactions in dogs, to best effect in combination with a corticosteroid. Also used to prevent vomiting associated with motion sickness and sedation in anxious car travelers. Do not use in animals with glaucoma, heart disease or decreased intestinal motility (constipation).
4. Pepto-
Therapeutic dose: 1 ml Regular Strength per pound body weight per 24 hours in 2 or 3 divided doses.
Example: 10 lb dog gets 10 ml total over 24 hours in two 5ml doses 12 hours apart.
Adverse reactions: Use cautiously and for short term in cats ( 24 hours or less) due to the aspirin in this medication. Bismuth will discolor stool black, but this is not due to harmful effects.
Commonly used for symptomatic treatment of diarrhea in dogs and cats. Do not use if there is mucus and/or blood in the stool.
5. Metamucil (psyllium)
Therapeutic dose: ½ to 1 tsp per 10 pounds body weight in each meal
Adverse reactions: None known other than intestinal impaction with over use with inadequate fluid intake
Commonly used as a gentle but effective bulk fiber laxative in dogs and cats.
