What do your dogs enjoy that keep them stimulated but don't necessarily need hours on end and could be done at home in between work meetings! DDog gets 1 long & 2 shorter walks a day (1 shorter one is loose lead work) plus I usually do a mix of the following but feel like we're both getting a bit bored with the same thing and need something fun and different to add to the mix
Scent work around the house/under blankets or in box/scrunched up paper etc
Hide & seek - me or a toy
1 session working on commands (sit/lie down/front & middle plus place at the moment)
He has kongs and lick mats - usually peanut butter plus training treats but any other suggestions welcome
