Aly,
I haven't ever given my dogs yogurt, but I do know someone that uses it frequently with her Golden Retriever. It is especially good when they are on an antibiotic...helps with tummy problems and yeast infections.
My friend freezes it in her Kong and her dog loves it. She uses sugar free plain yogurt. You might just check with your vet to figure out how much he can have, but I would think that in moderation, it would be ok for Reece to have it everyday.
Let us know what you find out.
