The Lab x Kelpie cross is a dog that is well-known in a small region, not well-regarded where they are known, and prone to a great variety of behaviors. The two very different breeds that produce this odd dog tend to create an animal that is intelligent, useful, and loyal — but in different ways.
These smart dogs might be too much so, meaning that there is a lot of Kelpie inherited. When this happens, these dogs are overly anxious, prone to barking, and ever-ready to react in a fashion to make things right as they see it. Then again, she may be a lot more Lab, which means she'll be laid-back, prone to playing, and comfortable with anything that is not an overt threat. Either way, this hybrid dog come from two hard-working breeds, so they tend to figure out things one way or another.
Loyalty is not a problem, although this trait may be exhibited differently from one Lab Kelpie cross to another and even within a single litter. Some will seek to protect you from anything that moves, and others might show their loyalty by just being there, napping near you, and waiting for the next task.
If there is more Kelpie in your Lab Kelpie, constant movement is the norm. If there is more Lab, then energy conservation (such as napping!) is typical.
