@tanza:
Could also be a reaction to some kind of bite… here is another thought... when did he have he last round of shots? But in the end, I think I would take a trip to the Vet... could just be a little ear infection going on... they can and do get yeast infections in the ears.. and I have found that puppies for what ever reason get dirty ears... and slight infections. Kobey had one when he was about 4/5 months old...
His second round of puppy shots he got on the 7th of this month. His next round isn't until the 6th of March.
I am going to call the vet this afternoon & ask them if we should bring him in. His ears do get really dirty with wax buildup. I have actually used a q-tip (he's gotten a little better) & cleaned them almost every other day in the past week because everytime I look down there I see some buildup. Maybe that itself is another sign that something more is wrong.
I will check his paws & rear tonight for any signs of an allergy but I examined him a lot last night (after noticing his ears) & didn't see anything else out of the ordinary.
