Fighting about letting the animals on the couch!

So we have 2 dogs and 2 cats. We have a small mix dog that weighs 5 pounds full grown, and a husky full grown. My husband lets the small dog and cats on the couch but not the big husky because she is big. This pisses me off because she doesn’t understand why everyone is allowed on the couch but her and it makes her sad. I told my husband either all the animals come on the couch or none of them. He disagrees and says she is to big but the rest are small enough to go on the couch.

Who is right? Me or my husband?

Edit- we do have a dog bed for our husky next to the couch. His reasoning is she wears out and damages the leather couch, which is true, because we use to let her on the couch and realized this. But I still don’t want her to feel like she can’t but the others can.
