Greetings, I'm Callum's other half and Leo's mum.
Leo essentially is an angel, and we've had very few problems with him over the past weeks - only the usual puppy problems that pop up and are quickly solved, but over the last two days, he's done a complete turn around, and decided no he wont sit, or come or do anything that we've trained him to do.
I'm not sure what triggered this, but it was first noted on Leo's first day of puppy preschool when he refused to come, then furthermore BIT me very hard in order to get away from me and play with the other puppies. Now Leo has nipped before but never bitten!!
Anyway, since Saturday he's been an absolute horror... and we can't figure what the problem could be, we've tried extra attention, trips to the park, treats. We also went through some small training sessions with him again several times. The problem is Leo isnt fussed on food rewards and isnt all that enthused with our positive reinforcements either....
Any suggestions? My parents have been breeding BCs for years, and we've never encountered a turn around like this.
Its upsetting me very much, as I love Leo dearly, and he seems to have become a completely different boy!!!
