Well, most of you will know all about Archie and his craziness. He is now officially knows as Archie-LoopyDoodle

and boy, does he live up to it on his walks - which is what I would like some advice and help on PLEASE from all you experienced doodle owners.
Archie is now nine months and a big, strong boy. His walks are a pleasure and we both really, really enjoy them apart from one thing

Archie is VERY sociable and loves all humans and dogs and greets them all with bouncy, bouncy, very excited tail and body wag, then just sits looking around when he has said Hello.
However, when we see another dog approaching he goes flat to the floor, as flat as he can, tail wagging, but he will not and cannot be moved. As soon as the dog is close enough, he sits, then when nose to nose, the whole body wag and very excited behaviour of meeting a new friend.
Thing is, he is NOT at all frightened or being submissive, which other owners think he is, it is just he so wants to meet the other dog that nothing will move him.
As soon as the meeting is over, he is super happy and walks off again, and is totally brilliant.
I just wondered if it is something he will grow out of, or if there is anything at all that can be done to prevent it. He is now 25kg and is the size of a retriever, so a big dog, and I want to try to rectify it before he is any bigger
Many thanks and I look forward to reading any tips/advice from you experienced doodle owners
Kirsty and Archie
