Not sure if anyone has come across this before but my 2 year old dog has started to refuse to walk when we set off from the house and will sit down and refuse to carry on and look anxious. Sometimes we stop and start and eventually she will poo and then she’s pulling on the lead and enthusiastic to walk. She’s been vet checked and nothing found to be wrong. She’s her normal self otherwise eating, drinking, playing. I was going to try a change of diet if anyone has any recommendations but otherwise not sure what to do. She’s better if we drive somewhere to walk or if she’s carried until ready to poo! Any ideas?
