Plan now. Make sure your dog has tags on.  Check to see that the tags are visible (sometimes the engraving gets worn off) and that your phone number is current (has your area code changed recently?). If you take your dog out of town for the weekend, get a "vacation tag".  I got one for Flip that says, "I'm staying with...." and lists his host's name and phone number.  Also, make sure you have current photo of your dog, and note any distinguishing marks (is that spot on his left hind foot or his right?).  If you need to provide a description of your lost dog for the humane society or for posters, it's helpful to have it accurate and current.

If you're home with your dog and you hear fireworks, make sure your dog feels calm and safe.  Put on music or TV to mask the noise (one student recommends watching a "war movie", since most dogs have learned to ignore the sounds from your TV and the fireworks will fit right in with the crash of the movie's bombs; another student plays mellow classical music and "reads" to her dogs instead!).  Act calm or even jolly, yawn, smile, and engage your dog in some fun activity if he or she seems alarmed. Do not inadvertently praise your dog for being scared by saying, "It’s Okay!", but show him or her that you are not bothered.  

Here's how you can help your dog deal with the stress:

DAP

You may wish to consider a product called "Comfort Zone with DAP", which releases a chemical which is supposed to be a dog comforting hormone. It often helps to calm stressed or exited dogs down (I have been using it with my own dog since the birth of our child disrupted our routine). See petcomfortzone.com for more information. For some "anxious dogs" it seems to really help take the edge off of their anxiety or intensity. You would want to use it for a week or two beforefireworks are expected. You can read about how some trainers are reporting success with it here. In the SF Bay Area, it is available at Pet Food Express.

Melatonin

You might also want to give your dog some melatonin.  Check with your vet, but the approximate doses are 1.5 mg for a dog under 25 lbs, 3 mg for a dog 25-100 lbs, and 6 mg for a dog over 100 lbs. Read about Helix Fairweather's experience with melatonin and fireworks here. There is also a doggy "tranquility herbal blend" from Tails By The Bay.

Anxiety Wrap

Finally, many dogs do very well with the Anxiety Wrap, a sort of "maintained pressure" vest that helps calm dogs down. It is available through SitStay.

Barbeques

Remember that cooked bones are dangerous and can splinter! If you let your dog enjoy part of a summer barbeque, make sure he or she gets boneless meat or raw bones only!

Other dangers include corn cobs and wooden shish-ka-bob skewers, which can be choking hazards; and onions, alcohol, and chocolate, which can be toxic for dogs. (Please bring any excess chocolate to your favorite dog trainer for safe disposal!)
