Oh my goodness, when Kale sees my BF, he goes bananas and flops over on his back and squirts pee all over! you literally have to stay out of the line of fire! haha
Your pup looks small still; puppys dont have full bladder control until they are 6-7 months old. Taking her out every hour to two hours and giving her the "go potty" command may help to alleviate some of the mess. Make it a fun experiance with treats and praise, while also letting her know its not playtime, its potty time. Taking her out on a leash to potty is ideal since most puppy go outside and just want to play and forget they have to potty till they get inside. lol : Kale is 17 months old and still pees when excited, but not puddles, just drops and squirts, gross to think about, but he is a male
To be on the safe side, I'd have her checked by a Vet to see if she doesn't have a bladder infection, that would make her pee a lot as well.
