Hi Guest,
Um, saw your posting here chastising the bawdy behavior of the crew. They deserve it, but it still brought a smile to me & that's hard to do since I"m still recovering from a broken & dislocated ankle...so thanks everyone for the belly laugh

But shame on you for subjecting an anonymous stranger to doggy humour
I do have a question for you since you did post, and especially so vague in terms as "wire" dog. I get a feeling that dogdom might not be your speciality---which is perfectly ok

Some of us know something about dogs
Do your "elderly parents" know you are looking to purchase a puppy for them? Reason why...I had a Wirehaired Fox Terrier a while back and while a wonderful dog.. he was extremely active as a puppy. This is normal. They are extremly smart and can learn easily how to get out, open stuff, and are just really active. They were bred for that. They also have fairly long life expectancies--well, as long as they don't escape and get hit by a car. 13-15 years are not that uncommon.
This breed and other puppies could be a bad match for someone who cannot move around fast or easily. A suggestion might be to look at an older and already mature dog that's already trained. I hope you don't take offense at my questions. I have experienced quite a few instances of adult children deciding that the parents need a puppy without even taking the time to consult them. These "surprise" situations created more hurt feelings and problems than were expected. None of them have ended well for the poor dog. Everytime, the dog has ended up in a shelter.
Please do not take offense at my words. I only mean to help.
