Hi there, this is Dr Linda, a UK based vet.
Congratulations on your new puppy!
I'm sorry to hear Millie has got this issue and understand your concern for her.
There are several considerations here including a muscle strain, a knee cap that doesn't sit in its groove as it should, hip pain etc.
As Millie is so young, her muscle will still be forming and will be quite weak.
Does she have any other signs such as paw licking?
I would keep an eye on things and ensure signs do not worsen.
If you can, do also get a video of this gait from several angles.
As she is not distressed by it and we would hope it will improve soon, we don't have to rush to the vet today.
However, it is important a vet examines her.
This can be done at her next routine check, which is presumably in the next week or so.
If the vet has any concerns from their exam, they may recommend some imaging.
Please do feel free to check back in if anything changes and to keep me updated on how her appointment goes.
It is also worth making the breeder aware, so she can let you know of any issues her littermates are having, or of any similar issues her mum or dad may have had in the past.
I hope this has helped and stay safe!
