I am suspect of Trifexis. Some dogs have issues with vomiting after it and I also heard something about the possibility of it causing problems with seizure prone pups. Might not be valid concerns, but this is a new product that is being pushed and I just don't like new products. I really don't understand the reason for it...Heartgard and Sentinel have worked for my pups for a month of Sundays. Going to stick with them! |
