were going to big bear lake and there odor stinks up the car. even after showers they start to stink how do i take that odor away?

feed them a good quality food and they do sell sented spray for dogs at the pet store.

give them a bath, take them to a vet to see if they have an infection

Give them a good bath, like take them to a dog wash place. But if you really don't want them to stink, don't let them swin in lakes, rivers, etc...That's what will stink your dog up in a heartbeat.

Make sure you have the right kind of dog shampoo, and not puppy shampoo, or one that's specifically made for a different breed/type. If it's not the shampoo, take them to the vet to check on infections, which can often explain mysterious bad orders on dogs. If that's not it, are you sure they're not farting? Most dogs tend to fart a lot more then people, and it stinks horribly. Or depending on where you live, they might have had a recent run-in with a skunk, fox, cat, bear... or a wild animals droppings/pee. It can be very hard to get these clingy orders off a dog, but tomatoes sauce usually works, even though they'll smell like spaghetti for a while.
