Gnasher
New Born Pup
My brother's GP, Henry, sometimes breaths loads quicker than my other GP, Gnasher. I don't understand this because Gnasher is older than him. Maybe he's freaking out about something, if guinea pigs do that. I am reasonably worried about this because when we bought him he was quite overweight and did this loads, but he isn't anymore but sometimes still has heavy breathing... help!
