First and most important, try to be home with your pet or have someone with them during fireworks.  So many pets are fearful and go stray during the Fourth of July, with the results being so many lost pets at the shelter, or possibly even hit by car.
Be sure gates and doors are secure, fixing loose or broken gates ahead of time.  Make sure tags and microchip information are up to date for both dogs and cats, and its best to keep your cats indoors.  If you cant be home, try to provide comfort so they feel safe.

Make sure dogs have a safe place that makes them feel secure…. A kennel, or safe corner with a bed.  Some dogs do well with  Thunder Shirts, an anxiety vest that applies pressure to the torso relieving stress and anxiety.
Turn the tv or Music up during fireworks to distract them.

Don’t wait until the last minute if needing sedatives from your veterinarian, as this requires an exam and they can book up quickly.

If your dog has never had sedatives, you want to have time to test the effects it may have on your pet too.

Never have them too drowsy and unable to move around.

Try to use training methods if possible, to get away from sedatives.  This could help get rid of the fear altogether.

Sound Therapy- Scary Noises is available for purchase online.  Created to help ease the fear of noises like thunder or fireworks. Give treats or playtime while the sound effects are being played.
Try other Training Methods  using loud noises at home.  And understand some dogs may never lose the fear, that sometimes we just have to accept that and find other ways to ease the stress.
Always be safe with loud noises around your pets ears. Check with your veterinarian, as extremely loud noises can cause Hearing Loss.  Never have them close to fireworks.

If there are a lot of fireworks being used nearby you can also provide Mutt Muffs to reduce the sound.

Have a safe and happy Fourth of July!
