Story

I received the dog in September 2025. I have papers on the dog showing birth, breed, neutered and current shot record. The dog is very timid, does not/will not sleep in a dog bed, and does not take getting shots well. Very good house dog and is house trained. Barks loud! I made my own schedule for taking the dog out daily to pee and poop. I take the dog outside 3 to 4 time daily. Dog does not run!

Spayed or Neutered,

Story

Meet Mr. Bojangles, a distinguished male dog around three years old, who brings both class and a dash of drama to the table! He would like to clarify that the vocalizations you hear from his kennel are not barking, but rather his intensive opera training in progress! Once he's out, this fancy-pants gentleman is incredibly chill and sweet, and he walks like a pro—no pulling, unless nature is making an urgent call. Mr. Bojangles is a certified foodie who appreciates a good gourmet treat but is just as happy with a classic peanut-butter bone. Basically, he’s a loyal companion who is effortlessly refined and ready to serenade his way into your heart!

Story

🩷I learned much about adorable Meryl Streep yesterday as we buddied up and attended CARE’S Adoption Event at “Tower Grove Pride” event. This adorable one and a half year-old pup showed her happy self from the moment she jumped in the car and was the perfect backseat rider. 🩷As we walked to CARE’S tent Meryl walked well on the leash. The event was well attended and this sweet pup was friendly and sweet throughout. As participants of all ages came up to say “Hi” and gave her pets she was gentle to everyone. As other dogs passed she was mostly indifferent being content and enjoying the moment. When this precious girl was tired she laid down and fell fast asleep and stayed like that as the action continued all around her. After her short nap we headed back to the car. This precious, perfect girl made the day’s event fun, happy and totally enjoyable for me her sidekick💕 🩷All I could think is this fabulous pup belongs in a loving home and hopefully soon! Meryl Streep, is a treasure and would be a cherished pup for many families. -Her eye condition is called Cherry Eye and is not serious and will be taken care of by CARES clinic when she’s adopted. 🩷She is at CARE STL for you to meet and possibly fall in love just like me🩷🐾XOXO

Bagels

Mastiff Mixed Breed (Medium)

Female, 1 yr 1 mo

St. Louis, MO

Size

(when grown) Med. 26-60 lbs (12-27 kg)

Details

Good with dogs, House-trained, Spayed or Neutered,

Story

Bagels is an adorable 11-month-old Mastiff mix (we suspect there's a little Boxer in her!) who is the very definition of a tiny lap puppy disguised in a big, beautiful body. This goofy girl has absolutely no clue how big she is, and she'll try to climb right onto your lap to melt you with her big brown eyes and sweet face! Bagels is a true Velcro pup who will follow you everywhere, convinced that your personal space is her personal cuddle zone. But with a face this cute, who needs personal space? She's quite smart, too, and is great motivated, which means she's quick to follow commands. Bagels is reliably house-broken (for the most part!) and loves sleeping comfortably on her own couch, going for walks around the neighborhood, and goofing around in the backyard. She's ready to fill an active home with love, snuggles, and endless laughs!
