My, my miss Maisy pie

Maisy bites on everything she sees. we try to walk her down, like two houses and shhe cant even do that because she bites on the leash.
She also stops every two seconds to itch underneath the collar to try to get it off.
Whenever i take her outside alone, she poops and I am the one who has to clean most of it up.
She pees in the house A LOT. We have to potty train her.
BUT STILL, she is the best and the cutest puppy you will ever see!!!!!!!!!!!
