Thank you for the information we will not use the product either

Which product are you speaking of? Yes manufacturers are out to seek their product no doubt about that, however heart worm disease is real and while not a huge problem it can and does happen, heart worm is carried by the mosquito (and yes they exist in The Villages) if your dog contracts it it can kill them and treatment to hopefully save them costs hundreds of dollars. I have seen a number of cases in my 13+ years working part time in a Vet. Ofc. I for one prefer to do what I can to keep my pet as safe as I can.

My 8 year old German Shepherd also had a bad reaction to the Tri Tak - she vomited for 2 days which is completely abnormal for her. She has the constitution of a goat :-)

I spoke to my Vet about this last Thursday and she contends that it is a rare side effect ( I disagree).

I am about to try NexGard (chewable) ... has anyone had any experience / feedback on this product?
