Close Up head shot - Diesel the Bull Mastweiler

Diesel the Bull Mastweiler at 6 years old—"This is Diesel. I rescued him from a kennel and he shares his home with another rescue dog named Jake. Diesel is like a big brother to Jake and luckily they have got along from day 1. Diesel enjoys walks and playtime with Jake. I'm a fan of Cesar Millan and learnt a lot from his training."

Description

The Bull Mastweiler is not a purebred dog. It is a cross between the Bullmastiff and the Rottweiler. The best way to determine the temperament of a mixed breed is to look up all breeds in the cross and know you can get any combination of any of the characteristics found in either breed. Not all of these designer hybrid dogs being bred are 50% purebred to 50% purebred. It is very common for breeders to breed multi-generation crosses.

Luna the Bull Mastweiler puppy sleeping on a couch

"Luna is a happy, confident, gung-ho puppy who has really benefitted from the advice on your website. She is my first puppy and I was getting overwhelmed by all her energy, and she was starting to show signs of stress from having to lead. Now she's right in the middle of Boot Camp, still fighting it a little but starting to relax. I think she's relieved that she doesn't have to be in charge anymore! We go for walks two to three times a day and follow your advice, she trots right along behind, head low, smiling. I didn't think I would be able to read her mind and catch her before/during a distraction but it's surprisingly easy!"

"This is our dog Ghana, shown here at 13 months old, 42 inches tall and 75 pounds. She is a Rottweiler and Bullmastiff mix (Bull Mastweiler). Ghana is a very sweet dog. She is very hyper when you first come home and when you give her loving, she calms down in about 10 minutes. She likes a lot of attention. She enjoys playing with other dogs including her half-brother, a full-blooded Bullmastiff. Although she is a house dog, she enjoys the outdoors. She likes tug-of-war, is a very fast runner and she likes to stand on her hind legs and dance with me."

"Look at our find! This 11-week-old male Bullmastiff / Rottweiler mix named Mick is the latest, greatest addition to our family!

He's very affectionate and always excited to see us, even if we've just been away for 5 minutes. His favorite play toys are our cats. He's very devoted to our family."
