I have a 3 year old black lab who, when given his monthly sentinel pill, becomes high-strung and spins continuously around the yard. Is this a common side-effect to this medication? Is there anything I might be able to give him to calm him down?
This is a very unusual side effect to the sentinal that I have never heard of before. I recommend that you change the heartworm preventative to another product. Benadryl 25mg can sometimes calm a dog down. Good luck, vetcare
