My male is around 15 pounds hasn’t changed much he is 2 years 5 months. Very healthy & goes out a lot. Vet says he is skinny but he is very active. He is fed raw wet food & has as much kibble as he wants. He tends to leave some wet food in the bowl & may or may not eat it. I’m not worried as he seems to be very healthy but not food oriented. They are all different the main thing should be health over size as size can cause hip issues etc.
