I agree with the other two. My Millie is an MT puppy farm cocker, too. I know how hard it is but I really think it is important in the first few weeks to hold back a bit. It is very easy to create a dependency or even a separation anxiety in these dogs by doing everything for them at the beginning. Provided you are gentle (as you obviously are), there is no reason why they shouldn't be treated like any other dog - rewarding good behaviour with a treat and refusing to reward bad behaviour with your attention. A dog that has had nothing will naturally try to grab everything that comes her way. In some cases they have only survived in their previous life by making sure they get 'first dibs' on food, prime position in shed, or any attention that's on offer from their feeders. It is as well not to let them develop this as a habit in their new lives. Play is probably the lowest thing on Summer's list of priorities at the moment. She almost certainly has no idea what it is and it may actually scare her. I am sad to say that my Millie never has learnt it, despite the very best efforts of her doggy friends (and her owners, too). But she was older than Summer when we got her - 5-6. She has, however, learned to love canine companionship, firstly with her collie friend Daisy and subsequently with our second rescue cocker, Cassie. She and Harvey will probably do the same, if you let them sort it out between themselves. One day the play light might even switch on in her brain. Fingers crossed for you. But don't get worried - it is very early days and you probably have a lot of other surprises in store. Most of them will be lovely if Millie is anything to go by.
