Puppy's front legs shaking

[OwlInAnOakTree]

I have a border collie puppy who will be 10 weeks old tomorrow. When he sits, his front legs often shake. He doesn't seem to be in pain, and I can touch his legs without him being bothered by it.

I thought at first it was probably just a puppy thing, but I've just googled and haven't found mention of it just being a puppy thing, but have found mention of all kinds of potentially worrying things. Does/did anyone else's puppy have shakey front legs?

My dogs front legs shake when he is anticipating something good. He’s done it since he was a puppy and he’s nearly 5 now. We’ve had no issues with it

Oh that's interesting, thank you. I wonder if it's just that. I notice it mostly when he goes out on to the patio, when he sits there watching movement through the hedge, tail wagging. Maybe he thinks all the people walking past are coming to see him. I'll mention it to the vet at his second injections, just in case. But that's reassuring to hear, thanks.
