I have a 7 year old must that is just under 20lbs. She never really ate that much food and never ate right when you gave her food. She just eats when she's hungry. Since she's getting older I decided to get a better dog food. I got her the blue buffalo wild cuts line. It's expensive but she's small and doesn't each much so I went for it. Same day I bought her the new food we were playing fetch in the back yard and she hurt her back. Pulled a muscle or something. The vet gave us a steroid medication she's been taking for the week. She is now eating as much food as we'll put in front of her. I'm wondering if its the new food and she really likes it or is it the steroids giving her an ungodly case of the munchies?
