I have to admit to taking Ollie out 1 day before the vets recommended 7 days were up. He's been fine. I'm sure being barked at won't have put your puppy off - it's just another experience and I'm told they live in the moment, so hopefully won't make any negative association with going out for a walk. Ollie now takes himself to the front door if the living room door happens to be open in the hope that he might get a walk - and it's a fine balance between encouraging a short walk - and not wanting to over exercise him. So for now he gets a short walk around the block or a trip to the park every other day - and otherwise has an 80ft garden to explore (which he also takes every opportunity to do).
This morning he did his first "barking at the birds" - there were some magpies making a racket in the garden behind us and Ollie was not impressed - even did a low quiet growl!!
He's now sat looking through the (closed) patio doors every now again glancing back at me with those pleading eyes as if to say "let me go and play, pleeeeaaaasssse" . . . in a little while Ollie - good boy!!
Hope you enjoy your walks together.
