It's hard when you live at another persons home. Chihuahua's are very needy when it comes to attention (well the ones I know). They are kinda like kids. I would think that Peppy may have taken that chi trait.
Is he inside in the day or night or mostly an outside doggy? Is he left unattended in the yard for long periods of time? Does Toby dig too?
