Get Your Dog Care Questions Answered by Experts ASAP
You may be looking at some type of contact dermatitis. Something that the dog is allergic to. If there ate new plants blooming then that can be a cause. There may also be a fungal or bacterial infection going on and in order to determine this the vet would have to do a skin scraping. If it is bacterial in nature then the dog will need to be on antibiotics. fungal infections will require special shampoos. I would bring the dog in for a skin scraping which can be done in the vets office and you would have an answer before you leave. Here is more on skin scrapings and allergic dermatitis.

Dogs can also get food allergies and this would cause a problem in the belly/groin area.It is not usually a new food that will cause a problem but a food the dog has been eating for a while.

Can you tell me what breed this is?
Also have you contacted the breeder to see if the parents have the same problem?
The only thing I see that is prone to this breed alopecia which means hair loss where there would normally be hair. http://www.thepetcenter.com/gen/dermatitis.html
I would go for a skin scraping to make sure it is not bacterial , fungal, or mites causing the problem.
I am also going to open this question up for another expert who may be able to help you further. You will see an opt out near my name, that will let others take a look.
Sally asked me to stop by to see if I could help you and your Yorkie with this problem. I'd like to get even more information to try to understand what is going on here.
How old is your Yorkie?
Why does he need diapers?
Does he have other medical problems (diabetes? kidney disease? - I am thinking of things that might make him urinate more often)?
Any chance you could take a digital photo of the blisters for me? If you can, I can tell you how to upload them so I can have a look - that would be VERY helpful!
You need to post your files on your question page, so the expert can see them. On your question page, there is a tool bar above the reply box at the bottom of the page. If the tool bar is not showing, click "show tool bar". Once you have the tool bar showing, here are the instructions for posting your files:
For graphics, click the tree icon and then browse to choose a GIF, PNG, or JPG. Upload and then insert it.
For zip files, PDFs, or spreadsheets, you need to use the link tool. Enter text (like "download this") in the reply box and then double-click to highlight it. The link is the tool to the left of the tree. In the upper right corner is a browse dialog box, which you can use to locate your file. Select it and then insert the link. Use the Preview button if you want to test the link and see if it works correctly.

I can also give you some suggestions on housebreaking your pup! ;-)
I suspect that your dog may have pyoderma - which literally means "pus-skin." A photo would help me to be more certain of this, but from your description I am very suspicious.
Pyoderma is a bacterial skin infection that is seen as red pimple-like lesions usually found in the groin area, and the armpit area. The little red spots may look like tiny pimples and they are filled with bacteria and pus. When they fill up larger they can look like blisters.
There are normally small numbers of bacteria living on the skin surface, but when they invade the skin like this it is called pyoderma. If there is just one patch, you may be able to treat it by washing the area with an antibacterial soap. One example would be chlorhexidine scrub (which you can get at pharmacies off the shelf in Canada and the USA). I suggest people wash small areas of pyoderma 3 times daily for 3 days. Rinse well. Pat dry. Then continue to wash twice daily for 4 more days. Watch VERY closely that there are no more patches coming up.
If this rash is in more than one small area your dog will need to go on oral antibiotics to get it under control. Oral antibiotics for skin infections are often given for 2-4 weeks in order to resolve the problem.
Here is more information:
So, please have a look at the links that I have provided. Do the photos shown look like what your dog has? If not, it would be very helpful if you could post a photo as I described above. If this does look like what your dog has, you may be able to resolve it if it is in a small area only (say, the size of the palm of your hand). If it is larger than this then your dog will likely need oral antibiotics, so a trip to your vet is needed.
Now, I think that part of the reason why your pup may have developed this problem is from wearing diapers. If the skin cannot "breathe" then it will stay warm and damp and this is a perfect place for bacteria to grow. So, it is really essential that your pup become house trained!
That said, Yorkies are notoriously difficult to train, in my experience. So... let me start by saying that this is going to be a bit of a challenge.
There is a critical age for house-training, and if a dog is allowed to pee and poo inside (even though it's on a blue pad) during that critical period, it is really tough to get the idea through to him that he can't do it anymore. Also, if your boy wakes up, thinks, "Oh, I need to pee!" and then does it on the floor, his behaviour is rewarded because now he doesn't have the discomfort of needing to pee anymore. So, it is really important to try to stop that pee from happening! More below about that...
Also, if you *catch him in the act* of peeing or pooing inside, then you can tell him NO and take him outside. But, even if you are 1/2second after he finished, there is no point in telling him he is bad. If you take him over to a puddle and tell him he is bad, he pretty quickly learns that it is bad to go near a puddle of pee, and looks guilty and repentant.
But he does *not* learn that he mustn't MAKE a puddle of pee. There is just too much else going on in his world, and he won't connect the discipline with MAKING the puddle.
In your dog's world, it is ok to pee and poo inside, on a blue pad. Now, because there were other pee smells around, he thinks it is ok to pee anywhere inseide.
What I would suggest you do is set aside a weekend to work on this really really intensely. Try the following:
- Buy some blue pads. Put them outside in the yard. Take your Yorkie to the blue pads every couple of hours. If he DOES do his business on them, CELEBRATE! Go crazy with praise and treats and telling him how happy you are. Take blue pads with you out on a walk. Put them down along the way to give him the idea.
- Hang some bells from the door handle to the back yard (or whatever door he uses to go out to pee). Every time the door is opened or closed the bells will ring. Now, if he goes and nudges the bells with his nose, TAKE HIM OUT right away! Dogs quickly learn that when they go out the bells go, and if they want out they can make the bells ring. Obviously the bells have to hang low enough for a short guy like your pup to reach them! Now, he has a way to ask to go out.
- If you can have a visit from a friend with a VERY well house-broken mature dog, that may help too. This dog can go outside and urinate in the area where you would like your dog to go. This may help him to get the idea!
Furthermore, I would suggest using the "umbilical cord" method of training for at least one whole weekend. It may take longer with your boy because he has been urinating in your home for 4 months and he thinks that is just fine! With this method of training, you put him on his leash while he is in the house with you, and attach his leash to your belt. Now, he is on an "umbilical cord" and can't get more than 3 or 4 feet away from you. Thus he can't disappear to go pee in the other room, and you will be able to catch him in the act every time! When he starts to posture, tell him NO! and scoop him up and take him outside to his blue pad on the lawn. Wait there with him until he does his business. CELEBRATE!
Lastly, you may need to resort to crate training your pup. A crate is supposed to be a dog's den, NOT a prison. They have a very strong instinct not to pee or poo in their own den, and will hold it as long at they can. A crate needs to be the right size - so he can stand up, turn around, and lie down. If it is too big, he will choose to sleep in one end and urinate and defecate in the other. Here are some links about how to crate train so it is a positive experience for you and your boy:
Good luck with this! If you feel my answer has been helpful, please hit the "accept" button. And if you have more questions about this, I'm happy to help.
My internet is running very slow right now, and the pictures I took are too large. I have to get my children and me ready for school tomorrow. Thank you for your help. I hope that I can catch you on Tuesday. Jami LItton p.s. I really need some help with his training as well!
That sounds fine! I think we may have been posting at the same time! I have sent you links so that you can look at photos of dogs with pyoderma (what I think your boy has) as well as housetraining information!
Best wishes! Fiona
Thanks for the photo! Yep, that looks like pyoderma and I would strongly recommend a visit to your vet to get some antibiotics. When pyoderma first starts, the pustules are red, but as it becomes chronic, the skin becomes hyperpigmented as you are seeing here. This little guy needs a course of medication to clear that up.
