UPDATE

6:50 AM PT -- A source close to Pete Davidson says he purchased the pooch for his mom, whose dog recently died. The new dog is currently at his mom's home. Pete is allergic to dogs.

Pete Davidson getting his new dog from a pet store and not from an animal shelter comes as a disappointment to the folks over at PETA.

Daphna Nachminovitch, the Senior VP of Cruelty Investigations over at PETA, tells TMZ ... "It's tragic that Pete didn’t seek out a borough-born mutt from a city animal shelter, because a scrappy New Yorker with charm, personality, and unconventional handsomeness could have been his perfect match."

As we reported ... Pete and his actress girlfriend Chase Sui Wonders picked up a cavapoo puppy last month from Citipups in Manhattan, and the dog is from a breeder.

PETA is urging Pete to consider adopting the next time he needs a four-legged friend, with Daphna telling us ... "Since shelters in New York and across the country are overflowing with homeless animals, PETA urges Pete to show some big heart energy by adopting, not shopping, in the future."

Remember ... Pete picked out the pup after seeing a photo of him on Citipups' website.

Of course, the whole reason Pete was looking for a puppy in the first place was because his dog Henry recently died at just 2 years old.

We covered it all in the latest episode of The TMZ Podcast, available on all podcast platforms.
