Hey My cocker spaniel Ollie loves doing tricks, but he gets annoyed if he gets tricks wrong or if he can't get the treat because I'm luring him into a new trick. For example, his Wave (holding right paw in the air) can be a bit hit and miss. He tends to get so excited about doing tricks that he literally leaps up in the air to try and get the treat. I only give him the treat when he holds only his right paw in the air, but he does get frustrated waiting for it. I suppose its good that he's trying his hardest to do the trick right, but is it ok for a dog to be so concentrated on getting something right and is annoyed when he gets things wrong? I never use harsh punishments, but I use sounds like ah ah or no, to signal that he isn't doing what I want. He's quite a sensitive dog. By annoyed, i mean he whines to get the treat, he's never aggressive. I don't use a clicker, should this be something I should introduce? I use treats to reward. He also does this when I do agility with him in the garden. If he misses a jump, he'll bark and whine. He's also so excited to be doing agility he sort of forgets to concentrate on me. Again, all I say is no or ah ah when he misses a jump. At the moment, if he goes the wrong way round the course, I just ignore it to avoid upsetting him.
