I used this product to cure a 2 year old turtle-aquatic..750mg in water he lived in alone for 3 weeks..he is better , not listing and returned to the community pond. I was thrilled to fine this. Reptiles do not do well with injections due to inguinal area being near kidneys. This method of use allowed him to drink in the water-infused with the antibiotic- naturally while eating. Great service .

This product is a lifesaver for a feral cat when he can't be medicated any other way other than sprinkling in food. My guy had an abcess and this worked like a charm! Sprinkle l/2 of a 250 in the food....

With 4 dogs, there's always some sort of issue, it seems! While not a proponent of overused antibiotics, there's a time and place for them, and it's nice to be able to provide what my dogs need without the costly veterinary office visit (and inevitable testing) that comes along with it. Will be keeping a stash of these from now on, to cover my bases for those 7-14 day stretches when I know that an antibiotic is in order for one of my fur kids!
