Lovely dog - especially the last two pictures. And how much energy do spaniels have? Makes me feel tired just watching mine charging around. I have a male springer and wish I could teach him to fetch a ball like that. Mine is a chewer, and he'll chase after the ball and bring it back to about a couple of yards, then whilst I'm walking towards him (he won't bring it any closer!), he has a good chew! If a tennis ball lasts him more than one session, it's unusual!
She's really good on that side... been a working dog all her life (pet mainly) mike the owner always gets her out on shoots etc. so she only grips the ball enough to keep it in her mouth. most of the ball chasing was done with the orange ball which is thick rubber. she's got a brilliant tempremant... we're hoping to have one of her pups when they breed from her next year.
