I wonder if anyone has any advice about indigestible protein and staining? My 2 year old Coton de Tulear X suddenly started getting staining around his mouth a few months ago. This also affects his paws a little and his bum (a lot) due to licking.
I've been emailing back and forth with the pet food company who produce the kibble I've been feeding him daily, mixed with a good quality wet food. They seemed to think he might have become suddenly allergic to a protein source and suggested I change kibbles. My dog won't eat anything but the lamb and rice kibble but he is not as fussy with human food or his wet food.
I was thinking the staining might be related to the colour of the wet food so I stopped giving him the lamb and rabbit varieties and fed him exclusively on chicken and turkey varieties. The staining increased. Then I read on a couple of Maltese terrier forums that the owners think chicken and/or turkey caused staining in their dogs, so I excluded that from his diet for a few weeks and started mixing his kibble with either salmon and rice wet or the lamb and rice wet. Yet again, the staining is getting visibly worse.
I have started to wonder if he is sensitive to Lamb as it's the only thing he has had consistently throughout the whole period but many people I speak to seem to think this is unlikely.
I think I might have hit on something though when I asked a pet food company nutritionist about the pig's ear I gave my dog about five months ago. He stained instantly after he ate it (it never occurred to me that would happen) but I trimmed a lot of it out and it started to fade over the next few days. Then all of a sudden, about two weeks later, I noticed his bum looked sore. On closer inspection, the hair around it was tinged red. I also noticed the staining around his mouth seemed to be getting darker again. I never made the connection at the time but the nutritionist told me recently that pig's ears are mostly indigestible protein and this can cause allergic reactions in dogs that can cause excess saliva. If that is the culprit, then should I be feeding him kibble at all now? From what I read, lamb meal is legally allowed to have up to 11% indigestible protein. If he is sensitive to that, could this be what is causing the staining? His stools also smell a lot. Again, from what I read, this could be a sign he is getting too much indigestible protein.
He doesn't get any eye stains, just stains around his beard, concentrated mostly in the corners, and anywhere he licks a lot (genitals, bottom, etc). He gets a little mucous in the corner of his eyes that can be tinged a little red but it is not copious amounts and I clean it away daily.
I am happy with the wet food he is on but the last time I tried him on that alone, he had giant, sloppy stools. I kind of feel owners have been brainwashed into thinking a dog should only do small, firm poos, but it did alarm me a little to see how much more he produced.
Finally, I've been researching dehydrated foods today. They seem good at first glance. Do you have any advice regarding this method of feeding?
Sorry for the long waffling post.
