Why is my Chihuahua itching, rashy, rubbing butt, and acting strange?

Updated On September 23rd, 2025

Pet's info: Dog | Chihuahua | Female | unspayed | 9 months and 5 days old | 4 lbs

My dog is a tea cup Chihuahua. She is almost 11 months old, and she is itching has red rash patches under her chin on her neck and is biting at herself. Also two nights ago she was freaking out very skedish and peed herself. Rubs her butt on carpet, and is very sleepy, and itching for sure. I checked for fleas and didn't find anything. Please help I'm scared she will dye. Also she had all three of her shots while getting older.

Oh no, poor Bitty sounds very uncomfortable at the moment! There are a couple of things this could be, and one is fleas. Even though you don't see any, it's still possible she has fleas. It could also be that she has mites, allergies, or ringworm. As for rubbing her butt on the carpet, this could be due to intestinal worms or impacted anal sacs. I would have Bitty seen by a vet for her problems tomorrow. The vet can diagnose what is causing them, and prescribe treatment for her. Tonight, try giving her an oatmeal or Epsom salt bath, as either may temporarily relieve her itching.

    What a cutie! Rubbing of the rear end on the floor can be a sign of anal sac irritation. He may need to have his anal sacs expressed by his vet. You can read more about this issue at: http://www.veterinarypartner.com/Content.plx?P=A&S=0&C=0&A=625 We can also see itching as a result of allergies or occasionally tapeworms. I would recommend bringing Tuesday in for an exam by your vet to check for these problems. If the anal sacs are full and are not expressed, it can make them prone to infection/abscess formation.
