Im in the same boat as you with Chip. I bought the strips but she refuses to go the loo when i need her too
Im off to the vets with her this afternoon with numerous problems, ive started to change her diet just incase. I have no idea what to do myself really, ive read quite a bit about it but im still baffled, Chips an old lady now though.
I will get back to you later and let you know what the vet advised .
