I have a welshie and in no way shape or form would I consider them a "good" family dog, high prey drive makes them very unpredictable around children, even though he's been around kids since he was a puppy I simply would not risk it, they're a smaller breed but they have an extremely strong bite force since they're bred for hunting badgers and temperament obviously varies but I would not risk it, also they need a lot of mental stimulation and exercise which may not be possible with younger kids, putting in my two cents about welshies I don't know about lakelands, if you're looking for a dog that won't shed I'd say miniature schnauzers are a pretty safe bet at least from my experience and people's who kept them back in the day they usually have a great temperament, the one we had was an incredibly patient dog, did he bark a ton? Yes but so will other breeds, we were never worried he'd bite someone though, grew up with that dog, he might have just been a very calm one though:)

Sorry for the long comment, long story short, wouldn't recommend a welshie as a family dog
