Hi everyone, my spayed female Chihuahua/Pomeranian crosses (aged 11 years old - 2.6kg, and 2 years old - 1.9kg) have both been on Purina Pro Plan Hypoallergenic dog biscuits and tinned mousse. The 11 year old has the biscuits, and the 2 year old has a mixture of the biscuits and mousse. That combination seems to help with them going to the toilet well! It is now impossible to find the tinned mousse anywhere. Is there another brand that you can recommend please? Or an entirely different approach to their feeding? Very open to hearing what could be best for my dogs. Thank you in advance :-)
