“I have used Sentinel from the time my youngest dog was born (2010) and it is wonderful. It's the only heart worm medicine that protects against fleas as well as heart worms. It is a little more expensive than the others but the extra money is well worth it. Strongly recommend using this product.”
“My dog has been on the preventive medication for 6 years. Allivet made it affordable for me to continue his care. Thank you Allivet for your great prices and ease of order.”
