I have 3 dogs, all puppies and am wondering how much they should eat a day, Gracie is a 10 month old basset hound, Savanna is a 8 month old weimaraner and Bella is a 4 month old miniature dashound any advice would be helpful thanks

What are you feeding? Most chows have a chart on the package giving amounts, or how much have you been feeding? The best thing is to evaluate the puppies using LongLiveYourDog.com - Life Span Study - Rate Your Dog
You might ask the vet to confirm you judgment. Adjust what you are feeding each puppy to bring it into ideal body condition.
