My 6-week Yorkie puppy is itching with no fleas or rash. What's wrong?

Thanks for using Petco Pet Education Center, formerly Petcoach! This is possibly due to allergies. It really comes down to figuring out what is causing his allergies so that they can be treated or the specific allergen avoided. A secondary infection is likely and also needs to be addressed. There are many things that can cause allergies though in most cases they can be broken down into 3 big categories: flea, food and environmental allergies. Allergies are usually worked up in a stepwise fashion starting with flea allergies as this is the easiest and cheapest to take care of. If not on a flea preventative, then it would be a good idea to get started on one. If already on one then it would be a good idea to change to something else (there are many new products out in the market). If not improved in 1-3 months then it is time to move on and check for food allergies by switching to a novel diet (new protein and new carbohydrate). If that does not seem to be the issue then you are left out having to check for environmental allergies which require blood and/or skin tests. Allergies can be very frustrating to deal with at first but so rewarding at the end when we are able to treat them effectively!

She could have an allergy, skin infection, or mites. If she is that itchy than she should be examined by a vet to determine the cause. Your vet can do a skin scrape, cytology, and/or culture, if needed, to help diagnose and then prescribe medications to treat. She may need an antibiotic, anti-histamine, corticosteroid, or other medications, depending on the diagnosis. Hope she feels better soon!

You will need to take your dog to a veterinarian for a skin exam. Your dog could be suffering from an allergy, mites, fleas, a bacterial or fungal infection. each of these requires a different treatment, so it is important to find out what is causing the itch. Your vet will do a thorough exam and maybe a a skin scrape. He will then discuss the options with you and then prescribe medications, possibly give an injection to stop the itching.

I'm not sure what the rash from Sky's bite would be - I'd recommend contacting your physician regarding that problem. It can be pretty common for puppies to have itchy skin. Fleas or other parasites still may be a possibility, even after a bath, so I think that it would be a good idea to have your vet examine Sky. They can also prescribe a safe flea medication for her.

If Prudence is wearing a collar, take it off for a few days. Check her over for fleas. You can place booties on her feet or a baby onesie on her to prevent scratching. This will allow healing to begin. Have her examined by your vet to diagnose skin infection or mites. If she has fleas or evidence of fleas such as flea dirt, you will need to treat her and the environment. Frontline Spray can be used on her safely. You will need to read labels of other topicals preventatives since most have age and weight restrictions. You can also discuss safe flea control with your vet.

Poor Lillie, those eyes look very uncomfortable. It is possible there may be mites, a bacterial or yeast infection causing such signs and your vet may wish to do some tests to identify any underlying factors such as hormonal disease. I recommend you full check up as soon as possible

Your puppy may be suffering from fleas and ticks, might have sarcoptes mites or allergies. If Tyson is only 10 days old (as you say in the description) he should still be with his mother. Puppies that young often suffer from bacterial infections which are itchy, and flea infestation. You should take your puppy to a veterinary doctor to have it examined. A mite infection can also be transferred to people and it could kill the puppy as can a severe flea infestation. Your vet can give you proper medications to treat those.
