My GSD Bernie has always been 'wirey'. But within normal weight range, just.
Since we got Pohm, the pup, Bernie has gotten thinner, as he leaves food for her, gives up food for her. Runs around more and plays with her thus losing calories with exercise. bernie is working stock, with very high drives. so a very active dog.
He's very healthy otherwise.
What would people recommend to fatten a dog up a little?
