I wasn't sure whether to put this in sports, tricks, or health as it sort of encompasses all three. I decided on tricks because there are certain tricks I want to teach that involve jumping. At what age can you start training for higher and more frequent jumps? I understand jumping should be kept to a minimum for growing puppies so you don't injure their joints but I'm getting impatient. I've never had a dog over 9kg's before Thor so I've been keeping his jumping to a minimum (he's 29.1kg at 10 months)--at his sport classes his jump training they're on the bottom rung still. Yet Thor loves to jump on his walks he'll go off in the woods and jump fallen trees, today he jumped about an 8ft spread over a 3.5ft high picnic table. So basically when can I stop being over protective mum and start encouraging him with jumping? I'm not sure I have the patience to last much longer.
