Our ophthalmologist, Dr. Wolf, relayed to us that he was at a conference and there was a big discussion about 4 breeds of dogs who were very slow to heal. I can't remember the others, but one of the 4 was the basenji. Nicky had a deep pitted abrasion/injury that took about 4 months to heal, required 2 debridements, but eventually healed perfectly. A year later she had another smaller abrasion, that is when he told us about the discussion at the conference. No one knew why those particular breeds eyes healed slowly, all agreed that quality of the final healing was not impacted, just the time it took to get there!
I found that very interesting, another unique quality of our breed.
