For the last month or so my dog has started whining when we walk. She has never done this before, its where we get to a certain part on the walk she starts to whine? So being paranoid the first few times it happened I check all her paws,etc. Nothing is wrong with her when she does it, it is also the only time she whines. Also why does my dog always have dirt around her mouth? I heard jack russells are notorious diggers but I exercise her so there is no holes in my back yard but a dog with dirt around her mouth? She doesn't eat dirt either I have watched her out the window before while she was outside she just sniffs a lot.....thats her thing lol
