I have a bull mastiff mix that I think that has hives. She has raised spots all over from her front legs back. She is not acting herself. What should I do.

I would take Midnight into the vet now. It sounds like she is having an allergic reaction, and she will need medication to treat it, such as anti-histamines or steroids. The vet can confirm she does have an allergic reaction, and can treat appropriately.

    This is likely an allergic reaction. As long as she isn't having trouble breathing then this can wait until your vet opens, but I would definitely get her seen today. in the meantime you can give her 50mg (2 adult tablets) Benadryl by mouth. I hope this helps.
