[Clinical data on the use of estriol-testosterone combinations in small animal practice].

A combination of oestriol and testosterone oenanthate was tried in 14 different indications on 110 dogs and 5 cats of both sexes. Two formulations were used, containing in 1 ml either 0.15 mg oestriol and 2.25 mg testosterone or 1.15 mg of the former and 2.25 mg of the latter. Dosage was 0.2 ml per kg body weight, by i/m injection. The criterion for success was the degree of functional restitution, without taking into account pathological changes, which were generally unaffected. Good or very good results were obtained in hip dysplasia, arthitis and patellar luxation. None of the 50 bitches treated showed signs of oestrus or irregularities in the cycle. The formulation containing the lower drug concentration seemed to give the best therapeutic results.
