These are great, I have a 4yo frenchie and he's never really had any digestive problems. A month or two ago he had a bout of sickness and diarrhoea and ended up with some injections at the vets. Since then he has intermittent issues and I bought these to try and settle this down. Anyway his stools are brilliant again, can't believe the different they have made. They've also improved his itchy ears.
