Losing black pigment on nose
|
|
| I have no experience with that but I did google it....Found it could be contact dermititis. Does she have allergies? Also, did she rub it on something to make it raw? Is she acting normal in other ways? |
| Didn't Darcy's Panda have Vitiligo? Panda ended up with completely pink nose and all the pigment around her eyes was also pink. |
| We've had Agnus for 4 months since his surrender, so everyday is a new day to learn about him. He seems perfectly normal to us. He will be 2 in April, so we are still in the puppy-toddler stage. After we brought him home, he had a check up with our vet and since he is sooooo tall, we needed to put on a few more pounds because the vet was concerned about his weight. His bones were a little too prominent, especially along the spine. Reading on some of his previous vet records, he had some weight issues and vomiting, but I think that was more stress related because he was kenneled at least 3 times a week due to the owners' jobs. Their vet was concerned about him being underweight and the vomiting. He has been fine with the vomit issue with us, and he feels like he has put a few pounds on. I didn't see any allergy issues in his records, so not sure what to think about the pink area. It's on the outside of his nostril, near where the nose meets his face. I will email our vet after the christmas holiday and see what they think. |
| Zeke has pink on his nose. Not sure if it was like that from birth or if it developed over time. He was 1 year & 3 months when we got him and his nose was already like that. And I've seen pics of lots of sheepies with pink on their nose.  |
| It think it's a good thing that a) you are observant enough to have noticed this happening and b) you have asked if it this change could be a sign of something that you should be concerned about. Typically once the black pigment is totally "in" it does not disappear. I did a quick search on vetinfo.com and found this discussion posted by Mike Richards, DVM in 2001: -------------- The various causes of loss of pigmentation of the nasal planum (the usually black portion of the nose) that I can find good references for are: 1) Dudley nose -- loss of pigment seen in a number of breeds for unknown reasons in which the nose is black when dogs are young but fades to brown or sometimes even white as the dog ages. 2) A transient form of the above condition may exist or it may be something else, but some dogs do lose some pigment and then recover the normal coloring of their nose over time. 3) Labradors, Golden retrievers, Bernese Mountain dogs and Siberian huskies may have seasonal variation in the color of the nasal planum, usually lighter in the winter and darker in the summer. The cause of this is not known, either. Some vets refer to this as "snow nose". 4) Vitiligo can cause loss of pigment of the nose and it may also be part of a syndrome of immune mediated disease in which hypothyroidism also occurs, so perhaps this is the link to loss of color of the nose and hypothyroidism but if it is, the hypothyroidism is thought to occur after another disorder causes the color change. Dogs with vitiligo normally have development of patches of white hair or white hairs scattered in the hair coat. I don't think that loss of pigment in the nasal planum only is likely with this condition. 5) Contact dermatitis can cause loss of pigment in the nose -- some dogs are reported to be sensitive to the plastic that is found in some feeding bowls, for instance. Continual irritation of the nasal planum from a cause like this might lead to loss of pigment. Usually the lips are also are inflamed or may have pigment loss if they are dark, too. 6) We see dogs with discoid lupus and with phemphigus that have loss of pigment of the nasal planum, usually patchy but sometimes most of the planum is involved. There are also usually skin sores around the edges of the nasal planum, on the bridge of the nose, around the eyelids or places like that. ----------------- This reflects what I was initially thinking, which is that it could possibly be related to hypothyroidism and/or some immune system response. If it were my dog, I would want to discuss with the vet having blood work, specifically to include thyroid testing, done on him. If you are using a plastic dog bowl, I would change that to stainless steel. Just my thoughts. Keep us posted. Linda Z (not-a-vet) |
Hi! Panda started losing her pigment when she was about 5...it started on the side of her nose. the vet told us not to worry, sometimes the pigment will go back...she had a perfect thyroid. her nose continued to change along with her lips and eyeliner  By the following Sept. she had gone competely pink and lost the cobble stoning on her nose as well....it was smooth and shiny  The vet originally diagnosed it as vitilgo, however, the more research that I did, I believed it was discoid lupus....which would explain the loss of cobble stoning.... Her nose was SUPER sensitive, I always tried to keep it moisturized, however, trying to keep a dog from licking their nose is virually impossible...Nivea worked great, it was thick..also, she would get sunburned on her nose, so I had to find a sunscreen without zinc...chapstick with a high spf worked well too...  I would personally have Zeke checked for discoid lupus...it is somewhat common in herding dogs... |
| I would think that if you're seeing a change in the pigment of Angus's nose, then you'd want to bring up with you vet the issues Darcy mentions. But I think for Zeke, his nose was like that when we got him almost 4 years ago and it hasn't changed. I will talk with my ex, however, about discoid lupus and the other causes of loss of pigment so that she can bring it up with Zeke's vet. |
| the loss of the cobblestoning on the nose is the biggest clue...in the pink areas, see if it is smooth or still cobbled..... |
| It seems to be on the smoother side instead of cobblestoned like the rest of his nose. He has a couple of smaller spots that I noticed too. I emailed our vet, so I hope to hear back tomorrow. The area around his eyes are still outlined in black. |
| we had the option of putting panda on predinisone, but we opted out...it may slow the progression but we just didnt like the long term side effects of it....Im not sure if there are any more ''updated'' alternatives....the WORST one EVER was a vet who suggested we tattoo pandas nose black again....wtf???? i cant imagine putting her thru that pain.....sigh |
