My Labrador has been on the same food since a puppy (Royal Canin dry kibble) and is now 5yo.
Last 6 months or so she's had softer stools (not diarreah) and has needed anal glands emptied twice as a result.
Vet recommended drying a different type of food to see if it could "firm things up"
She was going to email me some suggestions. She never did so I could call and ask but in the meantime, anyone else got any recommendations?
