Heidi is 14months old, been spayed and changed to Skinners food. I've noticed recently that she doesnt seem to have the energy levels she did. When we meet other dogs she plays but whereas she could just about outrun anything her size, now she cant and she doesnt have the stamina she used to either. Basically she has lost her mojo :lol: I am not bothered by it nor worried that she is ill, just curious as to why. Does spaying have this effect and that's why they are prone to put on weight? Is it a maturity thing in that she is no longer a puppy or Is it the fact that puppy food had 26% protein and Skinners only 20%?
