Congratulations on the new pup!
Have you tried giving her more food? One of the ways we learnt portion sizes appropriate for our pup was by giving her a little extra. She usually didn't want to eat beyond a specific amount. Plus-minus a couple of spoons and you'll get a good estimate of her diet. But from what you describe, it seems like you've got the portions right.
When we got our V home, she was exactly the same age as yours. We started training her almost immediately, because a). we weren't sure if should wait for her to grow up (you know how training books suggest you start early as pups learn best when they're young) and b). we were so darn excited for her to pick up neat new tricks! Now that she's almost 1.5 yrs old, I often regret having missed her puppy-hood. We were nervous and unsure and we ended up trying to discipline our V because we couldn't deal with the uncertainties and challenges that come with owning a pup.
She's grown up fine, very affectionate and naughty as ****. But I'd suggest you sit back and relax and have fun with your V. She will jump up, she will run around the house, she is likely to tear your cushions, chew on the furniture, and there will almost undoubtedly, be days when you will just want to give up and cry (I know I did) but understand this, no amount of training will help sort those issues at this young an age. It will take time for 'commands' to become habit. This is the time to play and bond. Enjoy your pup!
