I have a heart worm positive dog that was a stray in out neighborhood till about 2 months ago. One neighbor took her to a vet and got her cleaned up and all shots but the heartworm was positive. She could not keep the dog so she passed her along to me. I was going to take her to HSSM but so far it looks like I may keep her. I need to get her started on treatment but I really can't afford it. (Already spending about a grand a year I'm flea protection and heart guard for my other 3) What vet in the area would be the least expensive for treatment? There are so many I was hoping to avoid directly calling all of them. Terry, Wendy...any suggestions?
