So I am now thinking about our next terrier and I want to keep my options open and start researching breeders. It probably won't be for another few years. We want to get another terrier pup before Teagan is too old to raise it properly and happily. -Nothing too much smaller than Teagan, who is 16lbs, but for the right breed I would be willing to go smaller. - Good amount of Prey drive - Can settle in the house. - Must have wiry hair. And GO!
