i accidentaly found your page as i dont get a lot of info from a lot who follow me..hmmm.. but with that said i was suposed to i guess... you didnt say what was wrong with your dog but you have nothing to lose by giving him some ivermection. horse paste. at depending on pounds he wouldnt need much like a lick of it.. less than 1/5 of an inch.. twice a day... the vet probably might not order it and cost a lot.. i paid 10 bucks for it for myself!!! even... my dog was sick we didnt know what was wrong. vet did give him ivermectin cause she had no clue. i was kind of insistent in things but she did give me that. it was the pills for dogs ( i guess) and in 2 days what a difference.. by 4 days back to normal. honestly with as much as you would need to a small to large dog it would not only last a long time but if you want to use it, it is also safe. (took it for a week) i know it sounds crazy but nothing to lose at this time. ivermection has no or even very limited side effects. none deadly.
