Hmm not sure if I did but thank you for your response

So I have these brand new olive green jeans. I wore them on Sunday and it's Wednesday so they've been in my little hamper for a few days. I pull them out to go and do laundry and realize I have pink little dots on them. When I took hem Off they were spotless but than today they had spots. I do have 2 pets. But I don't think they could have gotten to them. Any tips on how to remove them?
