Barney not himself -staying out in garden
We have an 8yr old male miniature schnauzer who recently has taken to wanting to stay in the garden and sleep most of the day.
Only coming in to eat or get ready to go out for his twice daily walks which he is very keen on and enjoys.
He has good appetite ,kibble mixed with a small amount of something tasty added.
I wonder if you can give me any ideas as he doesn't appear so happy as he used to be . Very worrying .
