My dog's nipples are dark and she sleeps a lot. Is she pregnant?

Yes, it certainly is possible that Ruby is pregnant. The only way to know for sure is to have her seen by a vet. I would wait at least three weeks, then take her into a vet. At this point, the vet can do a blood test looking for the hormone relaxin which will be present if she is pregnant.

The timing and symptoms could point to a false pregnancy. Have a examined by your veterinarian for confirmation. Treatment is typically not required in mild cases. Symptoms should abate within 2-3 weeks. If they don't or her behavior worsens, your vet can dispense medications to decrease milk production and possibly tranquilizers/sedatives for anxiety. Severe cases can be treated with hormone replacement therapy. To prevent​ future episodes, having her spayed would be the recommended course of action.

It is possible that Bella is heading into another heat. While dogs typically go into heat every six months, they can go into heat sooner, and it's a possibility if her last heat was a few months ago. She could also be experiencing a false pregnancy if there's no chance she would be pregnant. I would have her seen by a vet in the morning for a definitive diagnosis as to why she is experiencing these symptoms.

It could be possible that Cheeky is pregnant if she mated with your male dog when she was in heat, but without seeing her in person, there's no way I can say for certain. I would take her into a vet today who can do x-rays to confirm if she is pregnant or not. Best of luck, I hope this helps.

Nipples getting bigger can be a sign of pregnancy. If it's been at least three weeks since Chloe was mated, you can take her into the vet to have a blood test looking for the hormone relaxin. This is present when a dog is pregnant. Yes, you can give a boiled egg for protein, no shell. I hope this helps!

She may be having a false pregnancy. If she had contact with a male while she was in heat, she could be pregnant. She could also have a hormonal problem or a mammary tumor. It would be best to take her to a veterinarian for an exam. The vet can also tell you whether she is pregnant. Unfortunately this is impossible without a hands-on exam.

It could be a false pregnancy, true pregnancy, or a pyometra (though fluid from the nipples is less likely with this issue). The only way to know for sure is to have her examined by a vet. As long as her appetite and behavior are normal, I don't think you need to rush her in.
