So I have had my little boy for about 3 weeks and he has fast become my best friend, baby, constant companion, etc. I have never felt this way about a dog before. I work with him a lot, training him and he is so smart. Anyway, last evening I took him out of his crate to go potty and noticed 3 dime sized bright red welts on his tummy and penis area, bright red rings with tiny little bites in the middle. They caused him no pain to touch and he's not itching them. They are not swollen. The only thing I can think happened is that yesterday morning I took him outside with me and tied him up to a tree with his harness and a 10 foot or so tie down while I did some yard work a couple of feet away and fed the chooks. He LOVES ants and will "hunt" them in the ground, head to the side, ears cocked, looking for ants and then trying to eat them. This is a new behavior that he has only developed in the last week. I am wondering if he didn't bite some bug that bit him back! I watch him for hours after I discover the bites and notice he's acting perfectly normal. As the night goes on they start to fade somewhat and today they are a dull dusky pink color. I combed through all of his fur and found no other bites than the ones on his belly area. Last night about midnight DH and I are watching a movie and Max starts snorting and doing that whole reversed sneeze thing that Chi's do for about 10 minutes on and off. I rub his throat and give him a drink and he's fine and goes back to sleep. Doesn't happen again all night. This morning, my DH and kids bring me breakfast in bed for Mother's Day and just as my husband puts the tray down on the bed we hear this retching coming from under the blanket where the puppy was sleeping and I fling back the blanket to find he had vomited all over the sheets and himself. Into the tub he went to get cleaned up. He has no fever or anything but he's been doing the snorting thing on and off throughout the day, nowhere near like it was last night. Very mild. I have no idea if the bites and the snorting/vomiting are connected. My husband and I have scoured the internet looking of pics of what the welts/bites look like but can't find anything that looks like it. Any ideas?
