Hi Gemma it's great to hear things are getting better for you. Ideas for indoor games, hide the treat I get lots of plant pots turn them upside down and put treats under a few I put them all over so he has to find them then tip them over to get the treat from under. I also use them the other way with toys inside that he has to find and bring to get a treat. I also teach him simple tricks, this seems to really wear him out so we get a bit of peace.
If you don't mind a bit of mess loo rolls or plastic bottles with treats in can keep him quiet for a while.
we too love the loo roll middle with treats inside and plastic bottles are a great idea too..mine get a loo roll each with treats in just before i go to work..they love them..the find it game is also a good dog knackerer..is that a real word
glad you are feeling better...it really is an awful illness..depression..as much as you dont want to feel this way you cant help it
but so glad you have taken it upon yourself to get out there
