I was walking my 5 month old shih tzu off her lead Thurs evening when she decided to run off the footpath and into a farmers electric fence. She let out a huge howl and yelped but seemed to recover fairly quickly. Friday night and she seemed a bit constipated - unlike her and we had to get up to her 3 times in the night for her to go outside - she has never needed to do this even as a young puppy. Last night (Saturday) the same - twice and then this morning she wouldn't touch her food. Her stools have been softer than usual but more of them. Could this be a reaction to the trauma of the fence, has she been damaged or is it coincidence?? Anyone have any experience of this? She seems a bit quieter but was happy enough when out walking yesterday. She has now eaten something but has left some - completely out of character!
