The advice and homework from the trainer has really been paying off! I've been doing work to help reduce his anxiety in the home through enrichment feeding, changing the picture around going outside, got to mat and crate games. He's enjoying the enrichment feeding and it's taking him 20 minutes to eat his meals not 30 seconds!

He loves his mat and it's helping to give him a 'job' when there's something going on outside.
