So, my boyfriend and I are 'Big dog' people, and mutt/rescue people. We had 3 dogs, my now 10 year old 90 pound choclolate lab/border collie mix, my 120 pound dobie rottie mix, and a 90 pound 3 y/o boxer/plott hound mix. We had a yard sale. We were closing up and getting ready to go to the beach when a family pulled up and bought a coffee table. I was helping load it in when a cute face popped out. I said 'what a cute weiner dog!'. To which the husband said 'do you want him? Were on our way to the pound now, we cant keep him'. We asked to see how our dogs took to him, It was kizmet. He was 6 pounds, severely underweight, and missing fur on his tail, with a crook in his tail that looked like it was broken. Its been almost 2 years since weve had this mini dachshund that we name Cooper. We finally have him up to 11 pounds, after medication for kidney/liver issues. He has Dachshund pattern baldness on his tail, and his tail still has a little notch from a break. Despite feeding him almost twice his needed food he still looks kinda scrawny, but is much better! However, my lord this dog is stubborn! No one trained him anything ( we think he was about 1 when we got him, almost 3 now) and that he had some level of abuse. I tried teaching him 'sit' the first week. He was so food/treat aggressive that when I pushed his butt down to show him how to 'sit' he turned around and latched on to my hand! 2 years later he knows 'sit' 'lay down' 'bang' and 'stay' (most of the time). For the last month we have tried the 'Cesar' way with food aggression, getting him to relax and submit before eating. After about 1-3 hours (depending on the day) he will stop whining and relax ( a little) but he never fully submits. For the last 2 weeks I have taken him on 15-30 block bike rides where he is at full speed, and he still isnt relaxed afterwards at dinner time. I guess my question is- are all dachshunds so stubborn? This dog is so serious that he will only open his mouth and let his tongue hang out and look happy after a 20 block ride. I think he is extremely high energy , but after 30 blocks, Im pooped! Also, I cant train him to 'beg' or 'sit pretty'. He hates sitting up? Any pointers?
