My 14 yr old lab, Honey, has deteriorated over the last month or two, she sleeps most of the day, and struggles to stand, often getting her back legs tangled and standing on the top of her paw instead of the pads. she is often incontinent of faeces, all of this we cope with as we don’t have carpets, so easily cleaned up, but my main concern is since Christmas she refuses to eat her food, only eating, Fresh cooked chicken or gammon , I am happy for her to remain on this food but I realise this is not fortified with the vitamins and minerals she needs, she has 3 yumove tabs for senior dogs daily, can anyone offer advice on her diet please.
