Story
Meet Cookie! This 100 lb lap dog is a total sweetheart that wants nothing more than to be next to you! In her previous home she lived with her littermate and 6 children ages 3-17 years old! Cookie very much likes to chew on things - what dog doesn`t?! - so she`ll need plenty of outlets for doing so like bully sticks, nylabones, and cow ears. Cookie really likes to lean her entire body into you while she`s getting pets, and lay her head on your shoulder. If you`re looking for a squishy, adorable, and sweet as pie pup, Cookie just might be the mastiff for you!

Story
Meet Miss CHULA Chula is a 2½-year-old Cane Corso Mastiff mix and a true gentle giant. She’s as sweet as they come and firmly believes she’s a tiny lap dog trapped in a big, beautiful body. This cuddle-loving girl adores attention, hoarding toys, and hanging out with her “siblings.” She’s currently living peacefully with our two 6-month-old Dutch Shepherd mixes and a Pekingese, and does great with dogs she knows and trusts. Chula did have a rough experience in the past after being attacked by a large dog, which left her a bit anxious around unfamiliar dogs. With slow, patient introductions, she may do well with another calm dog — but she would absolutely thrive as the only pup in a home where she can soak up all the love and feel safe. She’s potty trained, knows her basic commands, and walks well on a leash (though she’s still learning that she doesn’t need to lead the parade). Loyal, affectionate, and endlessly loving, Miss Chula is looking for a home that understands her big heart and will give her the patience she deserves. If you’re looking for a devoted companion who will love you with her whole soul — Chula might just be your girl.  If you are interested in adopting, please visit our website and complete an adoption application at www.elpasocountycanine.org/adopt ##2564189##

Story
I'm so excited to meet you!! Will you play fetch with me? I'm a very friendly girl and I love to meet new people! I like to spend a lot of time relaxing and cuddling, but I also love exploring new places and playing games. You won't find a more food motivated pup than me! I'd do just about anything for a treat!! I'd do best in a home as an only dog. General Socialization Notes: I love meeting new people! I am a very sensitive girl so I'd need a gentle touch. I love to cuddle!! I would do best as an only dog. I am very smart and very treat motivated. Does Rosie like other animals? I would prefer to be an only dog and spend time with my humans that way I get all the love! I am not sure about cats so a home without cats would be best. Does Rosie like children? I would love to be in a family with older children, 13 years and older. I'd love to play with them! No small children because I am a bit enthusiastic. Favorite Toys: I love frisbees, balls and Benebones! I am also a master at fetch. My special talent is catching treats in the air. I love that game! Ideal Home: I'd do best in a home where I have lots of space to run and play. I love my zoomies! I'd love a family that will give me lots of attention and training. I enjoy taking hikes and going on adventures. I'm a curious and loyal companion! I would prefer a home as an only dog to get all the love and attention from my humans.
