Poo Poo situation

Hi Helen. No she's not straining but was very lethargic yesterday. I'll take her in the morning if there's no movement today so to speak. Oh if it's not one thing.....the vet did give me some fibre pellets for her food maybe leave off those? what do you think?
Thankyou

Thanks guys. Her poos are harder after the NI diet which she's been on one month, but apparently hard poos are good for anal glands but cheese it is then. She loooves cheese too.
