Lavender oil can be okay for dogs to smell, but you should be careful and not overdo it. Some dogs might not like it. Here’s what to do:

1. Mix It: Always mix lavender oil with another oil like coconut or olive oil before using it near your dog. Use about 1-2 drops of lavender oil mixed with 10-20 drops of the other oil.
2. Don’t Put It Directly: Don’t put pure lavender oil directly on your dog’s skin, especially near their eyes, nose, or ears.
3. Use a Diffuser: You can make the air smell nice with lavender oil using a diffuser. Just make sure it’s not too strong, and your dog can leave the room if they want.
4. Watch Your Dog: Keep an eye on how your dog reacts to the smell. If they sneeze, cough, or seem uncomfortable, get rid of the smell.
5. Ask a Vet: If you’re not sure, talk to your vet, especially if your dog has health problems or is pregnant.
6. Get Good Oil: Make sure you use good-quality lavender oil. Bad oils might have things in them that can hurt your dog.
7. Don’t Let Them Eat It: Never let your dog eat lavender oil. It can be bad for them. Keep the oil bottles away from their reach.
8. Check for Allergies: Some dogs might be allergic to lavender oil. If your dog starts itching, getting red, or swelling, stop using it.

Remember, every dog is different, so what works for one might not work for another. It’s always smart to ask your vet if you’re not sure.
