Is my pregnant Pomeranian okay after miscarriage and rapid breathing?

There is a chance that the other puppies died as well. Take her temperature and if it is above 38.5C please Take Honey back to the vet. If there is a fever, she has infection which likely is caused either by dead puppies or by an infection that caused the miscarriage.

If she is spotting she should be examined by your vet. Bleeding that much this far after breeding is not normal. She really should not be bred if she has a collapsing trachea as it is a hereditary condition. She is quite young to already have collapsing trachea so it must be pretty significant - either that or she has something else going on all together. I strongly recommend you speak to your vet before breeding her - you need to get a proper diagnosis as to what is going on with her trachea and honestly, she should not be bred until she is her normal body weight.

12days is very premature for puppies (remember each week is roughly quivalent to a month in human pregnancy) and survival would be doubtful. Bed rest with frequent, small meals would be recommended and monitor closely for any fluid loss or discharge. An ultrasound scan by your vet to identify any problems with the pups or pregnancy would be recommended if she becomes any more uncomfortable.

I would be concerned there are additional puppies in there that she hasn't been able to pass. I would strongly recommend to have your vet take a look at her. Your vet will be able to take a x-ray to see if there are any additional puppies. If she does have additional puppies that need to come out and they aren't removed, they can cause a really bad infection in her uterus and make her really ill. I hope this helps.

I recommend a vet visit to make sure that she doesn't have any retained placentas or another dead pup inside. Both these conditions can set her up for life-threatening infection. If she is eating and drinking normally, and does not have a high temperature, she is likely ok.

It appears indeed that your pug had a miscarriage. Hopefully she will give birth to the rest of the dead puppies within the next few hours. Take her back to the vet in the morning to make sure she has had all puppies and does not have an infection. She may need antibiotics depending on the condition of the dead puppies and herself, as she could become septic.

At this age we would expect a small breed puppy to have a heart rate around 180 beats per minute and sometimes higher during excitement, so this is not a concern. The breathing can also be elevated at times in this high energy dog. These symptoms so far don't sound alarming; however, a general health check by your veterinarian isn't a bad idea to do in the near future just to make sure everything checks out ok. In particular we would want the vet to check for any audible heart murmurs or arrhythmias. I hope that things work out well for your pet Ginger moving forward! Best wishes and take care.
