Sorry to hear about Sugar and hoping for comfort for both Sugar and your family.
Interesting, this is the first I've seen Brittanys identified as a breed at risk for this condition:
Who is Most Commonly Affected by GOLPP?
Geriatric dogs, anywhere from 8 to 13 years, average age of 11 years.
Medium to large breed dogs, mostly Labrador Retrievers, but also Newfoundlands, Borzois, Golden Retrievers, Greyhounds, German Shepherd Dogs,
Brittany Spaniels, and even mixed breed dogs.
