Delightful! All the instances of Kincaid + dogs do not mix are good fun (though I especially liked the clever explanation for why Holmes comes to Dartmoor later than Watson in HOUN!) and it all comes so charmingly full circle in the end.

He wants to believe that Watson wouldn’t bring home a dog that would eat him alive. Not now, anyway. Before, perhaps, but they have an understanding now. Hee. :-) I don't know this 'verse except passingly from other Holmestice stories, but it sounds like you captured their charm and banter excellently. I loved Kincaid's outrageous lying about his accomplishments in the beginning, too, and Watson being so completely unfazed by it.
