My mum’s dog would only eat Morrison’s own brand food, not even the decent stuff.
Sister’s lab isn’t too fussy – generally a dried kibble (not sure which one), oh and shoes, rocks, slippers, toys. He did have to have a specialist diet as a pup as came with a nasty bacterial infection that took months to clear up.
I didn’t realise dogs were so fussy. Try having cats. Our fussiest being a ‘rescue’ that lived wild for about 9 months. Felix “As Good as It Looks” or **** off !! He does go mad for bacon, cheese, chicken and plastic ham.
