How about having a go at this online training challenge - very little space is needed. https://www.stoneleighrally.co.uk/c...ulG4E1j-DtJ3RdePQQJTRK95Ng6gVVtJnrMLuTbnS_XFU It is a 'bingo' board made up of 35 squares, each containing a simple training challenge - e.g. 'sit to down at heel', 'pick up placed article'. You pick a route of 5 squares down the board, video them and send them off for an award. Then you can do a route across or complete the whole thing for higher awards. The challenge is non-competitive - you just need to meet the standard for each exercise - and there is no closing date. Even if you don't want to video yourself, I think this could be fun to try and if you have a pup or young dog it could be a good way of covering some basic skills.
So I sent in an entry for 5 exercises (that we could already do) and have achieved a purple award. Do have a look at the exercises and have a go even if you don't want to send in a video. They are great when we restricted to a small space.
Thanks for posting this - I am collecting ideas of things to do indoors and that definitely going of the list
