I use white vinegar to get out smells, it can be poured in at the beginning or once the tub is filled up. About a 1/2 cup per load.

But I also take my big fleeces to the laundromat because my washer isn't big enough.

You might try Baking Soda and do an extra rinse. I use bleach and sometimes soda. They have some Bleach that are scented and rinse once or twice to make sure they are clean.

Thanks for the suggestions everyone!

Natures Miracle makes an additive for the laundry. When I wash pet bedding I use 1 or 2 capfuls of "Get Serious".

I throw Simple Solution into my washer. I don't have pups but I use it whenever I wash the dog bedding and towels and the like. I put maybe 1/4 cup into the detergent container with the detergent and about the same into the softener container of the tray.

I use bleach too, but I also use liquid fabric softener. I'm addicted to the smell of either Downy or Gain Apple Mango Tango. My fleece holds up just fine - I've used bleach for years, plus it kills germs.

I am a bleacher too. I use it on everything and rinse well.
