My first litter - over 20 years ago - had a puppy with strangles. She had scarring afterwards but otherwise lived a long, normal life until almost 13 years old. I did breed her several times, still have 4th and 5th generation offspring of hers, and only experienced strangles once more. That was a mild case with neck swelling, no pustules or scarring.

Thank you to everyone who responded. I really appreciate it. The puppy will stay happy and well cared for with me until I can find a good home.
