Luxating Patella

[Poodle wrangler]

Our standard poodle Charlie has started to dislocate his left patella much more often and I was wanting to have him seen again for ?

surgery.

Any suggestions for who to see in Canberra area?

We're planning to travel with him next year and don't want this to be a painful problem for him (if fixable).

Am open to dog chiro., but wonder if we can keep it up when travelling?

Not sure what's brought it on as it's both legs (as b4) but left worse than right.

Only thing I can think of is: Slight weight loss+ less walking (due to my slackness) causing a change in muscle mass, but ??.

He's now 3.

He had XRays at 9 months at Nowra.

Vet said XRAys normal and neither were easily dislocated manually back then.

No hip Xrays, only legs.

Also, any ideas on how much I need to budget if surgery needed?

He's a 24kg dog.

Thanks!
