Thanks for all the input!
In response, my pup is 6 months old. We feed him nutrisource chicken & rice large breed puppy formula. We have not had his thyroid checked but based on some of the feedback here I think we will. I have heard of the Dilute's and the trouble with alopecia however I was told by our vet that he is a little young to be showing signs of that? Anyone have experience?
He definitely never seems lethargic, he's either running or sleeping lol. He seems to be growing super fast but I assumed it was normal, his dad was 115 llbs and at 6 months our boy weighed in at 71 llbs?
I like the look of that meal plan Beaumont67, we may give that a shot. What do you all think of the food were currently giving him? Based on some online research we felt pretty good about it before? What are you all using?
Your vet is correct--while I've seen dilute dogs (all blue dilutes for the record)who are entirely bald as young as 6 and 7 months is it rare and usually the dog has additional coat or skin problems unrelated to CDA.
I do have experience with dilution in the Doberman. The article that Melbrod posted a link to is one I wrote years ago for a doberman list and I own a very nice fawn male (Ch Foxfire's Glad Toed Monster BN CD RE OA AXJ NF CGCA
ROM LC-10). Toad is now over 11 and still has most of his coat--there is a little thinning right behind his shoulders but the rest is still there.
Toad's coat started to thin when he was around 4 but I check thyroid (a full panel) at 2--mostly because I haven't had a Dobe since the 60's who actually wasn't hypothyroid eventually. When the thinning started I rechecked the thyroid levels and his levels were low (and for a Dobe that probably means they need supplimentation--thyroxine.) Again--6 months would be very young to see low thyroid levels but it happens occasionally.
But the picture you posted looked more like a dog with a bad case of staph--sometimes it's better to deal with a vet specialist (allergist/dermatologist) when they have something that isn't clearing up with whatever treatment your vet is recommending. And it isnt just fawn or blue that end up with hair loss because of folliculitis or staph--Dobe puppies are kind of notorious for repeated bouts of staph and most vets will tell you that it's because their immune systems a slow to mature--and since most puppies outgrow puppy staph I believe this is true.
My fawn dog was weaned on ProPlan Salmon and Rice (now labeled as ProPlan Focus sensative skin and stomach) and has eaten either that or ProPlan Chicken and Rice ever since. I've never had any dog who was allergic to chicken but I know people who have and there is no single food that is the right or best for one idividual dog. There are people who will tell you that all Purina products are poison (or Iams, or Royal Canin) or that dogs shouldn't be fed kibbles that contain corn but I have fed many of the kibbles that others don't recommend and have had dogs who thrived on them.
I think that a good basic diet (whatever it may be) will do as much as is likely to be done to maintain a dilute coat. I know fawns who were raw fed, home cooked or a wide variety of kibble who retained good coats. What counts for even more is genetics--I knew that my fawn was likely to have a decent coat because I knew other fawns from my breeders lines who had done so. So my fawn got the same diet that my black dogs (and my only red dog) had received and it worked for him.
The only suppliments he gets (and has gotten over time) have been fish oil from 6 months on and vitamin E which I give to any dog getting fish oil. All the dogs get either a spoonful of yogurt or cottage cheese and an egg daily--all of which are good for coats. If I find a great deal on some sort of meat I'll make a stew or if ground turn it into something the consistency of Sloppy Joe's and freeze it is daily sized batches which they then get with their dinners.
I don't know how often or what you are using to bathe your puppy but one of the major causes of dandruff is bathing in water that is too warm. Dog skin doesn't deal well with warm water and many years ago a vet tech came back from a seminar on bathing dogs put on by a panel of vet dermatologists. She gave me a set of instructions that were passed out at that seminar and I haven't had a dog with dandruff since. The water should be no wamer than tepid--that would feel cool to you--and I actually bathe my dogs in cold water with very mild shampoos. And I don't bathe them frequently. A short coated, single coated dog like a Dobe can been kept very clean simply by wiping them down with a terry cloth towel, wet down and wrung out. When bathing dilute the shampoo, wet down the dog and apply with a wet washcloth or sponge in the direction the hair lays. Use your finger tips to work the lather into the coat--don't scrub the coat with your finger nails and don't use things like rubber curry combs to apply and lather a short sngle coat--you can aggravate any existing skin problem by rubbing the hair back and forth--and warm water will open follicles and you can then drive the shampoo into the follicles which can cause an irritation which may end up with the dog with a good case of folliculitis.
Rinse the dog at least as long as it took you to bathe him--and then rinse once more--all with very cool to cold water. You can mix a cup of plain white vinegar with a gallon or two of cold water and use it as the final riinse to make sure you have all of the shampoo out of the coat. Shampoo left after bathing will aslo cause dandruff. Let the dog shake himself and wipe him down with a towel--and again in the direction the coat lays--don't rub it back and forth. Even in the dead of winter all my Dobes are dry in less than 15 minutes.
70+ pounds isn't all that unusual for a Dobe male puppy at six months or so--my fawn dog matured at 28-1/2" and in conformaion he showed at 90 pounds--when he finished his championship and we started training for Agility I took five pounds off (young conformation dogs are frequently shown a little fat to make them look more mature). He's weighed about 85 pounds ever since.
Large breed puppies grow very fast--gets them in trouble often when we, their owners, start thinking they are adults and shouldn't be idiots because they are 80 pounds and thier full height at a year--just smething to bear in mind. Toad was 28" and around 80 pounds when he started showing in the 6-9 puppy class. As I recall he was just over 7 months at his first show.
As far as his sire's size--a weight only goes so far--at 115 pounds I can tell you that I've only seen one Dobe who wasn't just plain fat at 115 pounds. That dog was actually 120 pounds and was 31" at the shoulder--that is the size a male Great Dane--Dobes should never be that big. There is no advantage for a male to be that large and many disadvantages. These dogs should be MEDIUM sixed--and at that they are pushing the limit a what we would normally call medium.
If you do a search using dobebug + fawn + dilute +Toad--you should find a bunch of posts I've put up about dilution in Dobes and maintenance of fawn Dobes.
Good luck with your boy--I hope you have as much fun with him as I've had with my fawn Dobe.
