I used to feed goats milk to my dog, he loved it, had to stop as he had a mild allergy to it.

It was normal, in a carton goat milk. Wasn't aware you could get powdered, probably not a good idea to feed powdered to a dog.

 

A splash in a bowl of water is good for encouraging dogs to drink, to keep them well hydrated for hot weather or sports. I wouldn't use it every day.

 

Not anymore. Didn't feel like i am doing better for my furry friend and stopped it.
We had discussion about that with the the farmers dog customer service https://the-farmers-dog.pissedconsumer.com/custоmer-service.html and i stopped with that immediately.
There are so many things which are much more useful for our furry friends.

 

Unless you have a specific reason for needing to feed milk I would not bother. Goats milk is far better for them than cows milk but neither is necessary for an adult dog.
