OUR puppy is 11 months and has been a challenge since we got her at 6.5weeks old. Our current challenge is resource guarding. We manage it day to day well by avoiding her the opportunity to pick anything up around the house. She occasionally gets the children's socks and we are able to trade with a high value treat. She has now taken to sometimes resource guarding the sofa and whoever is on it! She barks at the person approaching and yesterday showed some behaviour towards my daughter we haven't seen before and I'd rather not see again!! So, we have decided she is not allowed on the sofas anymore, for the mean time anyway. We have her on a lead now during the day and every time she jumps up we say 'down'. Sometimes she comes down of her own accord and she is rewarded with a treat and praise. Other times we have to encourage her with the lead and does not receive a treat. We must have done it over 50 times today and at the moment she just seems confused. Am hoping after another 500+ times, she'll get the message! Does this technique seem ok and do you think it is the right way to go? Open to any other suggestions too!! Thanks!
