My first dog was a Cairn Terrier named Pepper. I had the pleasure of having that dog for almost 19 years (I put her down when she was 4 months shy of turning 19). She was an amazing dog full of love & playfullness. She put up with me & my 3 brothers when we were youngers, HOWEVER, she was a nipper & had no problem putting us kiddies in our place when we got too rough or mishandled her in some way. In fact, it was that dog that taught me how to respect dogs (of course if we got nipped, Pepper didn't get into trouble, my parents asked "What did y'all do to the dog?"
).
As a pup, she was very hard to potty train. However, smaller dogs tend to take longer than larger dogs & terriers are pretty stubborn anyways. On the other hand, she trained pretty easily (sit, down, stay, etc.). She was very playful & tolerated most of our mishandlings. But she was quick to nip when we deserved it. She was also pretty nippy & guardian like with strangers. She needed LOTS of outside time to run & play....& DIG! Digging was a great hobby of hers & all us kiddies would go out & dig in the dirt with her. (My dad then built us human kids a sandbox to dig in vs. diggin up the backyard.)
She got along with a few other dogs, but was pretty DA. In fact, one of my APBTs will forever bear a scar on her nose from 12lb Pepper Dawg. :lol-sign:
As far as grooming goes, we had her hand stripped to keep her coat to standard for almost 10 years, but she always hated it so as she got older, we just started getting her shaved. She tolerated that much better for some reason, but once you start shaving a Cairn, their coat DOES change. It went from very coarse & wirey to somewhat soft.
I got Pepper when she was 6 & had her until I was 25. I would give anything to have that little girl back. She was my best friend.
