Can your brother afford to take Springen to dog daycare or something of that sort while he SLOWLY works on desensitizing him? Our daycare is less than $20/day. The issue with desensitizing Springen... while having to crate him for 8 hours a day... is that he's still going into that freak-out mode. The goal is to never push him to that point, to very gradually work on kenneling him without him showing any stress signals at all before you start building on the time he's in the crate.
