A huge number of animals are terrified of the explosions that accompany the celebrations. "They get so frightened that they dig out under the fence. They break the fence, they jump through glass. They do anything to get away from those firework sounds," San Jose Animal Care Center spokeswoman Julie St. Gregory said.
Animal care officers say 75 percent of dogs and 97 percent of cats in Silicon Valley are never reunited with their families.
To keep your pets safe on the Fourth of July keep them inside the house and stay with them if you can and make sure to put an ID tag on them just in case they do get away.
If you find a lost animal take it to your local shelter right away.
