My dog is 5 years old and is generally good about housetraining issues. However, sometimes he urinates in the house, emptying his bladder completely as if he is incapable of holding in his urine. I have noticed that his accidents are always around the time that I give him his monthly heartworm pill. Could there be a connection?
I have never heard of the heartworm pill having these side effects. I do recommend that a vet examine your pet just to make sure all is well. Good luck, vetcare
