I think my dog has a UTI, she's a dalmation and has had issues with her bladder a lot over the past 5 years. She's had

Hello and thank you for using Just Answer today.   My name is***** and I will do my best to help.  I am sorry Leia has had bladder stones.  What are her symptoms today that make you think she has a UTI?
Since I can't see her myself, some additional information may be helpful.   Do you know what kind of stones she had in the past?   If they were urate stones (which is a Dalamation thing) is she on a diet or medication to prevent them from coming back?

Thanks for the information.  Leaking like this can be from old age and reduced estrogen levels.
Why do you think she has a UTI?
Is she on any medication or special food to prevent more bladder stones?

Vomiting is not expected from a UTI.  The only way to know if she does have a UTI is to have a urinalysis done by a veterinarian.

Do you see any blood in her urine?

Usually there is blood with a UTI.   I suspect her symptoms may be caused by something else.

If it were stones I would expect you would see blood.   If she is on S/O she should not get stones, unless the stones were urate stones.

If she were mine I would start by doing a urinalysis, palpating her bladder to feel for stones, and because of the vomiting I might do a blood test to check her kidneys.

Is she still vomiting?  If she is you can try some Pepcid AC, from a pharmacy.  what does she weigh?
If she is drinking let her have all the liquids she wants.   If she is vomiting, do not feed her until the vomiting stops.

The best thing for the straining is to keep her well hydrated.  The more she drinks the more she stretches and relaxes and flushes out her bladder.   You can add water to her food, and/or offer her water, ice chips, Pedialyte, and/or broth that has no onion in it.

You are welcome.   Please let me know if you have other questions and how Leia is doing.  You can post additional questions and updates about this by going to My Questions on the Just Answer website and I will respond the next time I am logged on. I will also be following up with you.
Thank you for using Just Answer.

Hello; this is Dr. Rebecca checking in to see if you have other questions.

Thanks for the update. She may be painful when she urinates. It is worrying that the stream is small. I hope you can get her to your veterinarian soon.

You might try some Tylenol for pain but it can only be used for a few days. If she is around 45 pounds she can take 250 mg twice daily. Just plain Tylenol (acetaminophen); no Tylenol PM or other form.

It could be that there is a partial blockage, or that the muscles of her bladder are weakened, or that she has stones; there are many possibilities.  When there is a small stream it may mean she is not fully emptying her bladder so that can lead to an infection.

I am sorry she is still vomiting. You can try 10 mg of Pepcid twice daily for vomiting. It is in pharmacies. The generic name is famotidine.
