Joey here is a West Highland terrier and he did something not many of his breed have done before, he mated with a Rottweiler to create adorable little 'Wotties' puppies. (I assume the little guy used a ladder...oh and don't worry OSHA, I'm sure he wore a hard hat and a harness.) Teresa Patterson from Yorkshire in the UK (owner of both Joey and Zara the Rottweiler) was surprised they had mated and said she was unaware it had taken place until the puppies were born.
I was completely shocked, I didn't think nature would let this happen but at some point it did. The puppies have a lovely temperament like their parents. They are high maintenance as they want attention all the time. One of the puppies, Sparkie, which our son is having, follows me everywhere I go. But this won't happen again - Joey will be going to the vets soon.
