Story

Romeo is very sweet 6 year old boy but the vets think he may be younger. He would love to be a family dog and definitely wants to find his forever home, but can be protective of his people and his space. That being said once he knows you are part of the family he listens very well and knows many commands, sit, stay, down, shake, wait. He is slow to warm up to new people but once he has been introduced to you he is a gentle giant and big couch potato that loves to cuddle. He also really enjoys going for a ride in the car. It is not recommended to have young kids due to his size. He is good on the leash and knows many commands but needs someone that is not afraid of his size and can properly handle him. Experienced adopter with larger breeds is a must. No other dogs or animals in the household and not a good candidate for crates.

Lila

Mastiff Mixed Breed (Large)

Female, 2 yrs 7 mos

Pleasanton, CA

Size

(when grown) Large 61-100 lbs (28-45 kg)

Details

Good with dogs, Spayed or Neutered,

Story

Lila is a beautiful Mastiff mix living her best life as our resident gentle giant and professional couch potato while she waits for her forever home 💛 This sweet girl is equal parts lover, snuggler, and car-ride breeze enthusiast. If you have a couch and a car window that rolls down halfway… congratulations, you already have two of Lila’s favorite things. With new people, Lila is a polite little introvert in a big dog body. She may play it cool at first, but once you pass her vibe check, she’ll wander over for a hand sniff and some gentle pets. Lila is still very much a baby brain inside a giant body, so she’s working on crate training, impulse control, and remembering that manners matter. She truly wants to be good… sometimes her dramatic side just makes a guest appearance. Structure, consistency, and a confident human are helping her improve every day. Lila is a mastiff mix, which means she’s a big girl with an even bigger heart. She can be a little unsure of herself at times, but with confident leadership and reassurance she settles in beautifully and bonds deeply with her people. Because of her size, puppy energy, and chase instincts, Lila is looking for a home without small children or small animals. 📍 Fostered in San Jose, CA Apply to adopt Lila: www.cabullyrescue.org/adopt
