My Kona is 1 1/2 years old...he has developed a couple of pimple-like sores on his belly. They are hard and look like a chicken pox type sore. We have recently moved to a new home so he has been exposed to different grasses, weeds etc. It is also mosquito season and alot of ants around. He doesn't seem to even notice that they are there until I mess with them. No scratching or licking. I have another yorkie with no signs of anything. Any ideas?
