Then I found Just Food for Dogs prescription. It’s not inexpensive, but my boy loves it and licks his bowl clean at every feeding. I’m no longer stressed about his renal disease or that he’ll starve from refusing the other prescription options.”

I was hesitant to commit to a 30lb bag, but the ingredients were too good to pass up, and price was unbeatable per lb. My picky boy loved it immediately. The transition has been smooth, and he's lost 2lbs in 3 weeks, with great energy and a positive disposition. It's early [in] the process, but I think we found our miracle food!”
We [switched] our other dog to Diamond Natural Light, after he tore his A/C and had surgery on his knee. He was less active and it really helped him from gaining weight which was very important and he loves it. He is a very picky eater.”
