This is a serious question. Both my sister and I have owned female Pugs that seem a little slow, mentally. Is it possible for animals to be a little retarded, or is that just limited to humans? The Pugs that I am talking about were also over-affectionate, which I sure didn't mind at all. They are on this planet to be loved no matter whether they are perfect or not. She is perfect in my eyes. If anybody has an answer to this question, please let me know. Thank you.
