I live in Orange County and this is the land of the dog walker, doggies daycares etc. You definitely need to research these resources so feel free to write me privately for some recommendation
s. Hourly dog walker rates here are typically $15 an hour. Even if not every day, it is still worth it, so don't think all or nothing - even 2-3x per week would help.
Nine hours a day is too long to be in a crate. Why cant she be in the apartment loose if you address her health problems (she clearly has an infection or something worse so please get to a vet asap). If this isn't feasible, then an x-pen is more appropriate to give her room to move around.
If you need a vet recommendation, then also let me know. Depending on the diagnosis, look at
