More: this dog was due to be euthanized in three days so......when I got him he was heart worm positive, had mange, giardia, and every parasite available in Dallas. My vet thought he was 2 1/2 but I was told he was 4 1/2.....that was in 2015 and I'm hoping my vet was correct. He weighed 31 pounds when I got him. He now is an optimal 60 lbs.
