I had a Jack Russell “Terrorist”, too! I’ve often said that if JRs were a large dog breed, they would rule the world. Megs kept me on my toes .... lots of fun. She was a rough-coat .... looked like someone had plugged her into an electrical socket and she could definitely act that way, too. I had horses so she had lots to keep her busy - quite the mouser ... I took her through a couple of levels of obedience training (several folks told me that JRs couldn’t be obedience trained - ha!) and she was one of if not the best working dog in the class ... smart as a whip and she loved to “work”. We had a few arguments over who was ‘pack leader’ once in a while, but not often .... she growled at me as a puppy and all hell broke loose (for her) so usually all I had to do was say her name in a sharp tone & stare at her and she’d back down. She died in her sleep at 13 .... sure do miss her lively, happy spirit around here.
The rough/broken coats come from other terriers that were bred into the Jack Russel/Fox Terrier line over the years. They are the best but people always ask what kind of dogs. They are not very well known. One of my long coated ones is a super mouser, all he wants to do is hunt. The short haired typical looking Jack is a talented ball player and defiantly more high strung than the long coats. Yesterday at the vet clinic I saw a precious dog that would pass for a broken coated Jack. She was a Chihuahua West Highland Terrier cross. I could have stolen that dog! :D
