Sharp. Smelly. Exhausting. Bemusing. Aggravating. Wet. Chewed. Bouncy. Scary. Expensive. Restrictive
Mine's not quite 2 and is almost safe. As in hands, feet, trouser leg safe from teeth. But we still get bounced regularly.
All I can say is that you MUST socialise the little sod as soon as possible, as often as possible. Seeing the difference between mine and another the same age I am very grateful mine met lots of people and plenty of dogs, even if all he did was scrabble and whine to get to them when he should have been learning to sit
Mine is calm, unbothered and friendly off lead. On lead he still scarbbles and whines, I will be working on that next
They take the eyes of a hawk, hearing of one too. Patience of at least 11 saints. YOU need to be trained, so go to at least 2 types of trainer:
The Kennel Club type is good for basic commands, lots of dogs not doing stuff, aka sit and wait!
The other type are behavioural, and that means you as much if not more than the dog. They'll teach you how strong your bond is/can be and how to match your expectations to your dog.
Oh, yes. You do get the snuggles, the love, the joy of the walking, the unconditional love etc etc. But at almost 2 years and counting I am waiting for that to be the majority experience!
