hi we’re new to this site our vet nurse recommended taking a look after speaking to her today for advice on how to manage our 10 month adolescent boy Monty!! He steals anything not nailed down!! It turns into a great game of chase . We’ve practiced “leave it!” Since he was little, it used to work but not now even with high value treats. He’s also quite destructive eating his way through drywall plasterboard when in his pen while I go for a shower!! He had toys to hand long lasting chews and stuffed kongs !! Not sure what else to try . He does training class every Saturday morning and we’ve just had a 1:1 for an hour today to help with lead pulling . Honestly should have called him reckit Ralph !! Any advice greatly appreciated.
