Here you go. They do float and are pretty indestructable. I have needed to replace the rope a couple of times which is easy enough

Thanks Claire. They look like the ones I used to get prior to going for the foam balls that SB recommended (and that are fab, but expensive ... have lost three of them now ... which equates to roughly £30!).

Couldn't find thie link - can you point it out?

Nothing special, keep one dog on a lead, throw ball for other dog; when it returns, put that dog on the lead, throw ball for other dog.

You can start off with both dogs with handleless leads so there is no farting about with putting leads on and off.

Soon you will be able to tell both dogs to sit/down/stand, throw the ball and then nominate dog by name.

It is a good exercise to develop impulse control (and I find other dog walkers are really impressed by it, an added bonus)

Kirsty I havent read all the posts so please forgive me if its already been covered.

If you have two dogs that are willing to fight over a ball, would the answer surely be just NOT to take a ball out with them at all, therefore removing the trigger for a fight?

Thanks!

Something to go on to my list of things to train next!

Kirsty - sounds like it might be fun to train your guys on this

Thanks both - yes, definitely something I am going to train

Dawn - I usually take a ball for each of them on a walk so there isn't this issue - in fact, even when I have only had one ball in the past it has only been an issue once before. However, I like to take balls on many (not all, but many) of our walks as I do bits of fun training when out (and the toy is the reward) as well as giving them extra exercise (ie chasing or finding the ball) so don't really want to stop taking a ball altogether.

Sorry the link was for the slip rope....I didn't read it
and there you go...all explained

I would say so too, to avoid an issue - however that would be counter-productive long term, so finding a way of modifying the dogs' behaviour so that they can each still enjoy balls on walks seems good to me.

It's a bit different to avoiding other triggers - within the home for instance, where putting them in crates/separate rooms to enjoy bones or removing certain toys isn't going to impact on their quality of life to a great degree.
