Just curious, why would you stack antibiotics? It's one or the other.
It's bad advise to be mixing drugs like that... you either start at the top with Baytril or start with Clavomax and work your way up to Baytril if Clavomax doesn't work. Also, Baytril will cause joint problems in dogs under 2 months old.
Here's what a simple search on the internet brought up;

At home, clean the wound with hydrogen peroxide, chlorhexidine or povidone iodine. Do not use a tourniquet; because the venom stays in the area of bite, a tourniquet is not necessary. The tourniquet may cause circulation damage.
If you see your pet acting lethargic, begin vomiting or the wound becomes larger, it is strongly recommended that you bring your pet to the veterinarian. Treatment may be necessary to reduce these symptoms.
Your veterinarian will treat the bite wound and may give your pet antibiotics to prevent infection. Surgery may be necessary to remove the skin around the affected area, if other treatments do not heal the wound. Generally, pets recover fully from these spider bites after several weeks.

Either drug by itself that ushog recomended will work. Personally, I prefer Baytril, you only give it once a day unless by personal preference you like to go BID. All other Antibotics are BIDaily or every 12 hours.
Hope
you need a stronger antibiotic. Clavamox and Baytril together is probably what you need for the dog
