But I also read something about Pyoderma a bacteria that can be caused by flea and tick medicines dry food which is what he gets feed. pls help me figure this out!

It does look like Toby's skin is quite irritated! The small bumps could mean that there is bacteria in his skin (also known as pyoderma) and he should see a vet for examination and appropriate medications. However, there is usually an underlying cause for the itching and subsequent infection. The most common causes would be fleas, ticks, mites, or allergies. Allergies can be from a range of things, including flea saliva, food proteins like chicken or beef, or the environment like dust, pollen, mold, or grass. If Toby has a food allergy, he may benefit from a novel protein diet or a prescription dog food for allergies. These are good things to discuss with your vet. While you wait for his appointment, try to prevent Toby from further itching his inflamed skin to prevent further damage. You can cover him with a dog or human shirt or try to put socks on his feet. If he is licking then he may need to wear a cone/e-collar. You can try to use some hydrocortisone cream on the itchy spots, but don't let Toby lick it off!
