My 14 year old JRT cross has recently started peeing indoors when I leave the room for literally anything more than 10 minutes. I let him out regularly so I doubt it can be because he can’t hold it in. Today I’ve had to mop up 3 accidents and I’ve been home with him all day. Thank god I don’t have carpets but am at my wit’s end, is it time for nappies? Do you think he might have developed separation anxiety? (no sign of it before). I suppose I could take him to the vet to rule out a UTI but if it’s not that, does anyone have any advice?
