If the saliva is fresh and your wound is fresh then yes there is a chance for infection

risk of rabies in your situation is extremely low, but not absolutely zero. Rabies is typically transmitted through the bite or direct contact of infected saliva with fresh, bleeding wounds or mucous membranes. In your case, walking on the floor where a dog may have left saliva on its paws is a very indirect and unlikely mode of transmission, especially if your wounds are superficial and not actively bleeding. However, because the dog's health status is unknown and you have open wounds, it's reasonable to consult a doctor to evaluate your specific case.
