Can my dog get roundworms when on Sentinel for 3 months?If so what is the purpose of the medication? General Dog Discussions
This is my first puppy (Goldendoodle) He was born in July 2006. Took to vet and tested 3 times for worms. Put on Sentinel in Sept. 2006. Now is passing roundworms in stool. I know sentinel helps with heartworm and fleas but I thought it was to work on other worms as well. Why didn't it prevent this roundworm outbreak?
