Those a brazen deer. I haven’t seen but a couple in our little town. One young buck chased my puppy onto the patio, then stood near the table she ran under and just watched her.
One stood at our front door looking in. Haven seen any since, but our neighbors have seen some.
You said “puppy”. If the puppy is small, don't let it run after the deer.
When I lived at a lake, our community was mainly woods and full of deer and it was unlawful to hunt deer there. I had a Yorkie and the lady next door had a Yorkie. I did not let mine out to run around the woods. Yorkie’s are low to the ground and can get caught in vines, etc., in the woods.
Deer weren't afraid there and walked around our houses all the time. The lady neighbor let her male Yorkie out every day and he chased the deer, snapping at their ankles. Deer know that is their most vulnerable area and one day a deer stomped the Yorkie into bits.
Just be aware of that and protect your puppy, don't let the puppy stay around the deer.
