My dog is aggressive after spay. Should I continue her Trazodone?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed Large (61lb +) | Female | 71 lbs

71 lb lab/pit mix spayed 9/5 three days later she became extremely aggressive towards me. Took her to emergency vet who would only look at her through the crate due to her aggressiveness. Said it could be a reaction to the tramadol she had been taking for three days since spay. Started her on trazodone 100 x6 times day. Since then there have been a few periods of non-aggressiveness once when she had received all her does and once when there was 11 hours between doses. Should I continue?

I recommend to call either your regular veterinarian or the emergency veterinarian. Aggression is complicated and someone who is familiar with Jane is the best person to give you advice. I suspect they will likely continue the medication until she is fully recovered. Then again, they could also try changing the dosage or even changing the medication since it did not make her consistently calm.
I hope this helps and please feel free to post any additional questions.
