Hello everyone, I am with my hubby for a couple of days while he goes to school, and we left my 2 girls with a sitter and took Peeka with us, but anyways, the sitter just called and said that emerald has fresh blood on her vagina(or what ever you call it on a female dog )

she had her pups (well it will be 4 weeks this thursday) could this be just still having the babies or is this something to get her to the vet asap??? thank you
