the puppy stage!!

we’ve ended up acquiring an unwanted greyhound x staghound puppy, which is a happy surprise for us. we have two adult greyhounds, and one of them we’ve had from 3 months of age (he was abandoned with a broken leg, and our ‘temporary’ help ended up being lifelong! 😂) so we do have some greyt puppy experience, but damn! i forgot how zoomy they are in comparison to adult life. any tips? advice? we were a bit slack on training our former puppy, so we’d like to be a bit more prepared this time 😜 🐕
