Ddog2 has developed a penchant for eating used tissues. We live in a touristy rural area, so at this time of year there are loads of used tissues on and around paths where they have dropped out of people's pockets.
When he picks one up, the other 2 dogs think that it's a great game to chase him, so he swallows them fairly quickly. No harm so far, but it's getting to be every day, and it can't be good for him!
He is a retriever breed, so I don't know whether it will be easiest/best to work on bring it (and drop/swap for a treat), leave it, or drop it, or a mixture of all of them!
Any ideas?
