I am so sorry to hear that Google has an infection on his paw. Thank you for providing a picture. It looks like Google is licking or biting the sore area. It is very red and inflamed which is often a sign of tissue trauma cause by the dog itself. I would advise trying these tactics for the next 48 hours;
Place an ecollar on Google so he cannot get to the sore paw and damage further
Bathe the area with warm water once daily and leave dry and open
Place a cool compress on the sore paw twice daily for a few minutes
Some owners find that benadryl can help provide relief from itchiness for their dogs, which may help make Google more comfortable

Thank you for using petcoach!
