Hello,
We also live in San Diego. If you live in the North County (Mira Mesa area), I recommend Rancho Mesa Hospital for the vets:
Rancho Mesa Animal Hospital - Home
They are very nice, helpful, and affordable as well!!
For the Groomer, we haven't try that yet, Cali is 5 months only.
For training, we attend the Humane society classes, which are very good!!
