I got Sammy from a gentleman who didn t have long to live. He wanted Sammy to have a good home. He sounded like the perfect dog for us ... but our dog has been an only dog since we ve had her and just will not accept Sammy. He is good in the house and learns very quick. Ive been working with him ( with out the halter) to come, sit etc.. He really needs to learn to lead better lm 75 and have RA....
