I have recently acquired a new foster dog. He’s a little over a year and appears to be a field bred springer spaniel. At 36# he is on the very lean side, and I’d prefer to see him in the 40-42# range. He was treated for whipworm in July and has been on interceptor since.
In his previous foster home he was eating a Purina food; I have switched him over to Earthborn Holistics Primitive that I feed my girls. He is currently getting about 3.5 cups/day, which is about twice what my larger Labs get!
I did treat him with Panacur again when I took him, and he is getting various treats and frozen Kongs throughout the day. Do these dogs just have insane calorie requirements? Or is there something more calorie dense any of you recommend?
