question about amount of food to feed a puppy

Puppies can’t be overweight. As long as you’re feeding a good-quality food, let her have all she wants without getting sick.
It’s been my experience that the back of the dog food bags don’t recommend enough food.
Remember that puppies will grow to their right size regardless of the amount of food they get. You can’t stop them from growing up unless you starve them. They will show ribs first. You don’t want a pot-belly with ribs showing as that indicates worms. As long as her energy is up, you can’t see ribs, not pooping too much, let her eat as she wants.

Good luck!

i thought the same with brownie but i guess that's how big she's going to get and she's only 1yrs

Ask your vet to show you how to judge a dogs weight. You should not see ribs on a dog. You should be able to feel them without much pressure. When you look down from above her, she should have a indented area ( like a waist line) between her ribs and pelvis area. When your vet thinks she is at the right weight, try to keep her there. I feed my dogs according to their activity level that day. If they are very active they get a certain amount. If they're laying around all day, say do to the weather, they get less. Often they won't even finish their food on an unactive day. Beagles do love to eat and it's very easy for them to become overweight if they aren't active.

check the back of the food bag to see it should have the daily amount for her weight on there
