What's wrong with my dog's face?Or body? Bones and wasps, too

SUMMARY: Ancient history: Amber frothing at the mouth

Source: Friend Cathy's FB post about her dog rubbing and pawing at her face, and she found a stick that required a vet visit.

This medical emergency with my first dog, Amber, sticks in my mind and makes my heart jump even half a century later. 

She was about 2, and we went camping with friends. She was off-leash in the group campground and suddenly I noticed that she was frothing at the mouth, pawing at her face, rubbing her face on the ground--the frothing terrified me: What kind of poisonous thing had she  ingested?! Because what else could it be? As an inexperienced dog owner, I initially didn't know what to do, but eventually put my fingers into her mouth and found some small piece of bone that she had found and it had become wedged in her upper jaw, between the left and right side. 

Fortunately I was able to gradually work it out and there was no permanent damage. But I still remember that moment of horror and terror when I first saw her. Yes, as a relatively new dog owner, every little thing  that went wrong became traumatic for my poor heart.

I'm skipping over the part where, when she was about 3-4 months old, I looked out into the back yard and she was standing listlessly, head and tail drooping, taking slow, unsteady steps, and drooling. Human Mom rushed out to her and she did respond a bit. I managed to get her into the house and, in the process of setting her down, noticed that little bumps covered her stomach. Exploring: Her whole body. Hives?! I figured it was an allergic reaction to something. Fortunately was able to get her to the vet right away, and she was already feeling a little better by the time we got there. I don't recall their treatment, maybe a shot of prednisone or something? They thought maybe a bee or wasp sting. 

Fortunately I never saw that reaction again. And, for the 7 years I lived in a house whose yard border was covered with shrubs with those red hairy flowers that attract bees, she would stand out there for hours, trying to catch the bees (and sometimes succeeding).

Apparently I'm not skipping that part.

That's all  there is for now...

Amber,  at about the age of the allergic reaction.
