What is your opinion on what is better?........ a skinny Julie whom eats hay or a better weight Julie whom will not eat hay? She lost weight and I started feeding her oats and treats/more greens/pellets to fatten her up. The vet checked her out and said she couldn't find anything wrong and to fed her more of these things. She gained weight but stopped eating hay. I bought all kinds of yummy tasting special hay to mix with her timothy hay and cut back on the other foods and worked with her. She is finally eating hay again but has lost weight again. What should I do?
