Hi

I have asked this question in the past ,my little Rosie is a heavy coated ruby girl of 2 she is healthy in all respects has no allergies or fleas that I know of has just had her glands emptied but in the morning when they all race up the stairs (apart from Lily who is now camped out in her own crate in our bedroom ) and jump on the bed at 5.30 and all have a general stretch and scratch Rosie then starts chewing her feet .This is quite an energetic chew and ends up with her feet soaking wet but I do try and stop her by diverting her attention someplace else.
Why does she do it and is harmful in anyway.
