In my opinion, overreaction to quick movements or loud sounds does not indicate abuse in the past. It does indicate reactivity and that is common in small breeds who are always alert, just like the YT, since they are aware of their small size and often skittish around unexpected sounds and movement.
Correction is key. So, whenever he acts like he's going to bite, for whatever reason, ensure that you say 'NO' in a firm voice. Then, wait five seconds after he's stopped biting or snapping and give him a treat.
My dog has never been abused and he acts the same way around things he's unsure of and correcting the problem in the above way has rectified a lot of unwanted behavior.
Hope this helps. |
