Camomile will do little to calm a dog that is fearful of fireworks.  You are better keeping her in a leash attached to a harness and walking her out for short trips to release herself.  

Every year dozens of dogs are lost when they run away due to fireworks – some are never found again so be very careful when she is outside.

Putting her in a crate in a darkened room where she is less likely to hear the noise is also a good idea. 

Try a thunder shirt or similar product to help her in the future.

Thank you so much for your response! But I am aware of that – my question is how quickly this happens. So, wiill 24-48 hours make a considerable impact? His ears have been gently cleaned, and he’s been given his allergy meds.

I’m going to leave the medical part of your question to our vets, but I do have an observation regarding what makes a reputable, ethical breeder.

Unless the person from whom you purchased your puppy titles (as in, they earn titles through showing, obedience trials, etc…not just AKC registration) and fully health tests per the Chihuahua Club of America, they aren’t what I would consider ethical or reputable. Here’s a lot more information: http://www.chihuahuaclubofamerica.org/health-committee-mission/

Read through the links on the right sidebar. And maybe look into an insurance policy to cover potential health issues. Petplan and Truepanion seem to be two of the best…avoid VPI like the plague, they’ll just take your money.

We took two separate stool samples in to the vet, then while my wife had the pup there a small worm was left on her shirt by the pup. Vet said it was a tapeworm so I’m assuming that’s what it is.

Plus had deurontinal more times than I can count.

If it’s prescribed by your vet, sure.

If not, I wouldn’t.  I would, instead, keep the doors and windows shut, blinds down, AC on, and run the TV or radio.  A trick I saw mentioned was pop a bag of popcorn (the all natural stuff, not the stuff loaded with butter sauce) and every time fireworks go off, make it rain popcorn.

I would also invest in a Thundershirt if you don’t have one already.

I would have gotten her to the vet today when they were open.  Sudden masses are usually not good…can mean a tumor or infection.

Thank you for rescuing!  I would plan on a vet visit once they’re open, just to make sure he’s alright.  All new pets should be seen within 3 days, anyway.

Sudden changes in urination (location, frequency, etc.) could mean a UTI, ESPECIALLY in tomcats.  Please get him to the vet for a urinalysis.
