Picky eater or something else?

I have a 6 month old beagle and she has never eaten much. She will eat a little bit at a time, generally 1/4 of a cup and 1/2 cup at most in one sitting. I have tried various food flavors and brands with different broths and toppings June 18th she weighed 12.79 pounds and as of August 7th she weighed 13 pounds. She is active and loves to run. I don't know if she is just a picky eater or if something else is wrong. I am waiting on a call back from her vet. She is still teething and I know chewing hurts her mouth. What else can I do to ensure she is maintaining a healthy weight and adding enough weight on for proper growth?

Hello! The first thing that you need to double-check is, how much should your dog weigh and how much should she be eating? It is easy to Google perameters for certain breed puppies of certain ages from a trusted website - I could do that for you now - but if your pup were to fall outside these perameters, it would be worrying and still somewhat unhelpful. You would still need to know whether you had a perfectly healthy puppy of a different breed or age to that which you were expecting, or whether there was some serious health condition, for example. Until you have the basic information double-checked by your vet health professional, it is hard to assess what your pup should be eating.  Early years nutrition is extremely important, so we strongly advise getting this checked right away.  Luckily, a lot of vets will do very reasonably priced puppy checks. Best of luck - and please let us know what you find.
