I hate flies

(WARNING - THIS POST IS VERY GROSS!)
So we noticed Snickers was walking weird and had his tail tucked in between his legs and we got worried. We knew that he had some matts in his hair so we decided to lay him down and try to cut them out because we were thinking maybe it was just pulling and that's why he was walking weird. We went in the garage and started brushing him and right away I saw a maggot crawl out of his hair on his back. Kevin was brushing near his rear end and said he saw some raw skin and found more maggots so right away we loaded him up in the truck and took him in. The vets said not to feel bad - it had been really rainy and wet, and a couple days earlier he had had an upset stomach, the poo got stuck to his fur back there and they said it doesn't take long at all for flies to come and lay eggs and then you have a maggot problem. And man oh man, did he have a problem! They had to shave up half of his back and one swipe of the razor and 'hundreds of maggots starting coming out'!!! They had burrowed under his skin and the poor thing was in pain. Snickers is a tough cookie. He is 12 years old now, has lived his whole life with three legs and he is doing so well! He stayed over night and was on meds for a week for the infection, and his back looked terrible and raw but you could tell he felt better right away. Poor puppy!!!
