The pain-relieving effect of carprofen and tolerance to the drug were
investigated in 805 dogs that were lame as a result of osteoarthritis. The
dogs were of different breeds, ages and bodyweights and of both sexes, and
were selected from 51 veterinary clinics. Each dog was treated orally by its
owner with 4 mg/kg carprofen for 84 consecutive days. Twenty-four dogs were
removed from the study because of side effects, and 55 left the study for
reasons unrelated to the treatment. The condition of the dogs and the benefit
of the treatment were evaluated by the veterinary surgeons and the owners
after 14 days, and at the end of the period of treatment, when 194 of the dogs
(26·7 per cent) were no longer lame, and 357 (49·2 per cent) had
improved. The period for which the dogs had been lame before entering the
study significantly (P<0·01) affected the results and the rate of
improvement. Too much exercise during the 84 days of treatment caused some
dogs to relapse.
