H currently has Advocate each month and Profender 3 monthly. I keep hearing about the 6 monthly flea injection and I'm thinking that might be better for him as he hates the monthly treatment. What happens about worm treatment though? I presume I would carry on with the Profender but I know Advocate also covers other types of worms. How can I make sure he's covered? (Please don't suggest a worm tablet, that will never happen!)
Thanks in advance
