I was recently given a couch that had belonged to a dog person. I vacuumed it up and it looked great, I brought it inside and by morning my whole house smelled like dog. That's a bit weird when you're used to cat smells.

I sprayed it with Natures Miracle and ran the rinse-n-vac over it with Tide for a soap, then followed it up with a rinse in clean water. Put a fan on it for a day and now you'd never know it was ever in a house that had 2 dogs.

I don't see why that wouldn't work for your doggie bed. Good luck.
