West Highland terrier, Joey, mated with Rottweiler Zara shortly after entering family home .
Teresa said: “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 and they want attention all the time.”
Zara gave birth to a litter of 11, but left Joey to take care of them. Pictures speak volume .
