I have a wonderful, huge Great Pyranees. I eats good, but is so thin. What can I use to fatten him up? What kind of a wormer? Maybe it's tapeworms? I don't know, but since all this terrible heat, he has just lost so much weight. He seems to feel just fine. And does a wonderful job taking care of the goats. I've only had him since around Spring time, but he has lost weight since then. Any help would be greatly appreicated! Thanks!
