The Bernese Mountain Dog was purchased by Liz and Tom Hewitt when he was eight weeks old.

The couple had wanted to get a dog for a while and Tom's only requirement was that they got a big dog.

With Bear set to hit 50 kilograms when he's fully grown and be about 70 centimetres tall it's safe to say he fits that criteria.

The pair had seen Bernese Mountain Dogs out and about and liked them.

After doing some research they fell in love with the traits the breed typically possess.

"It was the size that attracted us to the breed initially then we kept hearing all these great things," Liz said.

Bear fits the typical Bernese Mountain Dog personality to a T.

"He has such a loving personality," Liz said.

"He is so loving and incredibly loyal.

"He's very playful being a puppy but he is pretty lazy for a pup.

"He has his spurts of energy then he's done.

"He's very stubborn and likes to push the boundaries but also loves to be a good boy and told he's a good boy."

At the moment Bear's favourite thing to do is "hide" things under the clothesline.

"Whenever he gets something a shoe or a toy he runs outside and puts it outside under the clothes line," Liz said laughing.

"If there is anything missing we look for it there first and 90 per cent of the time Bear has put it there."

The best part of welcoming Bear to the family was the companionship.

"My husband is a farmer so he is away from home a bit," Liz said.

"To have a dog here is company and companionship.

"It's someone else to love in the house."

Liz hadn't owned a dog for at least 10 years and was so ready for Bear but Tom didn't share the enthusiasm initially.

He didn't feel a strong need for a dog but has been surprised by how much he loves having Bear around.

"For him it's a whole new experience and he is amazed by how much love you have for them [your dog]," Liz said.

"He did have all these rules but Bear can't do anything wrong in Tom's eyes now."
