Puppy won't poop on a walk
My 16 week old puppies have just completed their vaccinations and we have started walking them outside. However neither of them has pooped or had a wee on their walks, but they do both as soon as they are back in our garden :-( we have tried walking them at various times, including first thing in the morning - not letting them out and asking them to go as we would when we let them into the garden but nothing. We have even taken our resident older dog with us and praised him in front of them when he performs but no response! We are particularly frustrated as the person we bought the puppies from hadn't had them vaccinated and they were 11 weeks old when we got them - this has considerably delayed their socialisation as they have only recently been able to go out. They have spent the last 5 weeks confined to the garden & kitchen and have done so very well settling in and with their housetraining etc! HELP!
