Paddy didn't need any encouraging to get in!
After awhile a guy turned up with two collie dogs and tennis balls. These dogs were divers. Their owner would throw each dog its ball - then each dog would dive off a log to get it.
Paddy was watching intensely.
And decided that maybe he could do that as well.
Mostly, he was all legs. No co-ordination. And all about the splashing!
With a little more practise it might be his new favourite thing to do!
