I hope all goes will with Dixie. My two guys are a constant source of comfort as well as energy for me so I know how you feel. I have 6 pets, all if which are rescue and I figure that all the years I've given them are better than what they would have faced without me. Your dogs are daggone lucky to have you and things will turn out as they were intended. God Bless!!
There is also a type of worm that is hard to detect and we went through that with one of our cats. It requies a human prescription and is very hard to get rid of. It took several fecal tests to narrow it down.
