Border Collie Terrier Mix Care


Both border collies and terrier sheds are moderate to high. They have a double coat and hence regular grooming is required.

You would also like to bathe them once in 4 to 6 weeks.


Both Border collie and Terrier dogs are energetic. Border collies were bred as a working dog to herd and Terrier dogs are known to be energetic. Hence you would expect a highly energetic dog.

Be prepared for long walks and enough playtime to physically and mentally stimulate them.


It would both be easy and difficult to train this dog.

As he is intelligent, it would be easy for him to learn the commands that you would want to teach. But at the same time, he is independent and can be obstinate so it would be difficult to make him follow.

Consistent and positive reinforcement training is recommended for him.
