What's a good way to fatten up my dog?
I have a 5 year old Great Dane that is losing weight rapidly! We recently took him to the vet and they checked him for parasites or other factors that way be causing this, but they found nothing. They told us to switch his food from Benaful to Just6 while feeding him a whole, raw, chicken once a week. We did that and he started to gain weight and looked BEAUTIFUL. A little while later, he started to lose weight again, we feed him twice a day and have never missed a feeding. Now he looks worse than ever. We are thinking of switching him to Purina One, any suggestions? Please help!
