I imported my native Brazilian terriers from Canil Terrier Brasil kennels, which started w/Uberfox some of the best Champion bloodlines in Brazil. Similar to the American rat terriers, fox terriers, or jack russells these dogs are very alert, perky and intelligent. They weigh about 15 lbs. They love to play, but are also excellent lapdogs. They are wonderful with children and good with cats too. They make good pets and farmdogs. As watchdogs they will only bark to get your attention and then leave the rest up to you.
