My name is ***** ***** I’ve been involved professionally with dogs in the health and behavioral fields for over 18 years. It will be my pleasure to work with you today.
First thing would be to stop the pups from nursing. They are old enough to be eating puppy food exclusively. The problem with extended nursing is that a dog may develop eclampsia or breast infections (mastitis). Let me give you information on each of these conditions .
If your dog is experiences muscle weakness, muscle spasms, tremors or seizures, limb paralyses, she needs to be seen now as it is possible she has eclampsia. Calcium supplements, Tums, cottage cheese or goat’s milk may help, but it might not reverse the symptoms quickly enough.
Here is sites with more information on this.
Mastitis is generally first noticed as a swelling and inflammation of the breast. While it is easy to treat, it can be deadly if not treated quickly. Mastitis is caused by bacteria entering the nipple and gaining the upper hand leading to infection which often can enter the blood stream and thus infect other parts of your female as her immune system is already under the stress of having pups and nursing.
Now it really isn't that unusual to see some redness in the abdomen when a dog is nursing pups and since a dog's temperature is 101-102.5F, we frequently think they are hot to the touch since our body temperature is lower.
Puppies develop worms from mom. Worms lay dormant in the mom's intestinal tract until she she becomes pregnant at which point they hatch and end up being passed to the pups. So when you deworm the pups, mom should be dewormed as well so the pups are not contracting worms again from mom. In addition, all fecal matter in the yard and whelping area has to be kept clean so the pups don't become reinfected.
Worms can cause a dog to vomit especially after eating as a heavy worm load may thrash around when food is in the intestines. However, a protozoan infection can also cause vomiting and diarrhea as well. Let me give you informaton on worms and protozoan infections.
What I suggest you do is have a stool sample checked at the vet to see if she has a protozoan infection and worms if you are not already treating her for worms. If she does not have an infection or worms, you might want to have her seen if it continues or she has other symptoms. Check her temperature with a thermometer rectally and see if she has a temperature. If a temperature is present, have her seen as a uterine infection could cause vomiting along with a temperature.
I just saw your other post. Given her body condition, and amount of vomiting, I'd go ahead and have her seen by your vet. Definitely stop the pups nursing. One way is to cut the arms and neck out of a t-shirt of a child or use a tube top to put over the breast area to prevent the pups from nursing and also help protect the breasts if they should fill with milk. I'd wait until you have her seen to use that trick but take the pups away now. I'd have her seen as soon as possible.
