Hi Linda,
I posted this link on another query concerning Westie Behavior.. Taking the 'quiz' might help to answer some of your concerns.
West Highland Terrier Club USA has an online
"Profiler questionaire" "The West Highland White Terrier Profiler will attempt to analyze you and your environment and provide recommendations about how compatible a West Highland White Terrier might be for your household"A friend of my mother-in-law had a Westie that had completely dominated her household. The dog passed obedience trainining, but the owner failed it. She was a sweet dog, but very much out of control. When we visited, the very nice owner showed us all of the areas she had chewed, ripped up, destroyed in a year's time period. It was pretty sad to see how this was not a personality match made in heaven. I felt awkward when the dog latched on to me and did what I asked her to do, yet completely ignored her owner. I don't know if they're still together or the owner surrendered the war.
Westies are very independent spirits and obviously not for everyone (is there such a dog breed? ). I have a westie mix (with dachshund) and she's been a real character in the 8 1/2 years we've had her. But we've learned to anticipate a lot of trouble that she could do :)
Make sure that at the very least, you have a secure yard and somewhere safe you plan to leave your dog during your absences. Mine was crated for her first two years with us (whenever we left the house). I knew she was safely confined and my home would be intact when we returned.
She was a rescue that suffered from terrible anxiety separation...plus a bit of creative explorication (explore/extricate). We allowed her to earn her freedom through the years...but we still close the doors to the kitchen with its bins and the bathrooms with their tissue when we leave the house :)
good luck with your puppy
