Could really do with some opinions. We have a 10 year old Llasa who has always had the same food which is hi life semi moist food, it looks like mince, not the chunks. This is the only dog food she's ever eaten. She will happily eat human food. She has gradually been going off it, she picks at it. So today i thought I'd get her some wet food but she's not touched it. She would happily eat chicken, beef etc but not dog food, does anyone have any suggestions?
