I am the proud owner of a lovely bull terrier dog called bully whos 8yrs old ! over the last year or two hes started to lose a lot of weight and we cant work out why and hes starting to look very skinny ! I have took him to the vets who gave him a blood test witch came back all clear ! they allso wormed him! The touble is he has never been a big eater and has allways been a dryed dog food dog ! He is more of a picker at his food instead of eating loads in one sitting if you know what i mean !??! I walk him for an hour and half a day and he lives for it ! hes super fit and if you watched him run round you would see how active he is! but hes just getting skinnyer by the day ! i feed him wellbeloved ! anybody got any ideas on how to fatten him up or on what i could be doing wrong! I think the world of him and would hate the thought of him not being here gruntting and growning at me ! please help!
