well for such a young pup, I would be looking at all those meds he has taken. I am switching to Bravecto next mth. My vet says it doesn't go into all their organs like Trifexis. currently my 3 yr old 10# is on sentinel and advantage, but he loves the water so the switch is a good idea for me. he vomited the trifexis the time I tried it. hope others post comments. |
