I bought a flea and tick collar for my daughters 6 month old dog, it said for small dogs under 10 lbs. so I thought it was safe. We put the collar on the little dog, and thought no more of it, with in 24 hours I notice that she wasn’t acting normally, heart was pounding and she was having some sort of temors. She has just spent 3 days in the care of her vet, receiving IV’s and meds. Toxins cause temors she had been posioned, by the flea collar that I thought was perfectly safe. Now we are playing the wait and see game, she is still having tremors, the vet is trying to control the tremors with meds, will my 11 year old daughter lose her beloved pet? Please never use an over the counter product on your beloved pet.
