Our staffy cross is maybe a leetle portly and we will have to get her weight down a bit, she currently has half a tin of pedigree chum and 100g of barking heads twice a day plus a couple of doggy biscuits over the day, are wee feeding her too much? she is walked 3 times a day with quite a long walk in the afternoon, she is about 5, lazy and couldnt care less if she was never waslked again, other than feeding her less I am at a loss :(
