  1. I have a 2 year old female Chihuahua about 5 weeks pregnant. I want to know how many puppies she will have, but I can’t afford an ultrasound or the vets.What should I do? She had all her shots and is very healthy. I love my little girl so much and want to do what is best for her, but I don’t have much money. Any advice?

    • Hi Kathleen,
      Chihuahuas often have difficult births and require a c-section, given the bulbous shape of their heads. Your pup definitely needs an x-ray to determine the number and size of pups. The mom and puppies can die during delivery if the puppies are too large to get through the mom’s pelvis. Please seek veterinary care. I hope things go well!


    • If you don’t have much money, quit letting her get pregnant….poor dog will suffer at your lack of expense….

      • That was rude ..

        • no it wasnt, it was the truth. Truth seems rude but fact is this woman has 0 money to provide care for her pregnant bitch – do you really think she is at all worried about the care of her dog stating no money for a vet or xray. You would do whatever you need to in that case for the poor dog and pups lifes.

    • Kathleen,
      How did everything turn out with your Chihuahua?

  2. When will the puppies start moving

  3. I have a 3 year old Rottweiler that is about 7 weeks pregnant. I noticed she explexed a pup not fully developed. Are the other unborn pups in the same danger.wat should i do?

    • I have a 3 year old yorkie she got pregnant her first heat about 10 monhs old she did fine you may find yourself helping her as I did my yorkie was scared and didn’t know what was going on or even what to do as far breaking the sack around the puppies so I had to help her in that area just be calm and reassure her everything is ok and offer her water she will be fine I even had to cut the cord on a couple of them until she caught on.

    • Stop being Backyard Breeders!!

      US shelters are over run with chihuahua’s and chi mixes. Please stop the insanity! And it is cruel to let puppies become mothers. Spay your dogs!!!!

  7. Will a female dog have puppies right on the 63 day

  8. I have an American pitbull. I believe shes pregnant , but then again she isnt that big to be as far as she is. She is supposed to be due any day now. Her due date is between the 26-30 of this month. Could it possibly be she not that big because her first pregnancy and may only end up have one or two pups? Or if shes this far pregnant, would i be able to legit tell? Im so confused and anxious. I jus want to know lol

    • Mine are due around the 24th and I can easily see them moving. She was also in her first heat and we did everything possible to avoid it. I could tell she was Prego before that weekend. Not sure if that helps or not…

    • Did she tie w/a male? If you didnt see a successful tie she may have a false pregnancy, ours did first time. She was w/ a male but didnt tie successfully. She showed all signs of pregnancy & acted like it with her body too. Only way to confirm is vet.

    • Did your pitbull ever have her puppies? And if so, when did she finally show? I have a wirefox terrier who should be day 52 today. She is fatter and has a tiny pouch when I pick her up but otherwise acts completely normal. This would be her first litter, so I was trying to stay hopeful that she is, in fact, pregnant and is not showing as prominent due to this being her first time stretching her muscles. Very curious how common it is to not show, thanks!

  9. I have a Yorkie /Poo more Yorkie small trying to figure out her due date but I have read that they give birth like a week early .wondering how true that is .This is her first litter

  10. I have a 3 year old yorkie she got pregnant her first heat about 10 monhs old she did fine you may find yourself helping her as I did my yorkie was scared and didn’t know what was going on or even what to do as far breaking the sack around the puppies so I had to help her in that area just be calm and reassure her everything is ok and offer her water she will be fine I even had to cut the cord on a couple of them until she caught on.

  11. Help my chi is 13 months old and has mated with my other chi she is approx 3 weeks pregnant but has gone off her food and is very picky in what she eats, she will sleep for around 18 hours during the day, please is this behavior.

    • Kathy, it is very normal for bitches to go off their food and even throw up due to morning sickness. The decrease in energy levels is normal as well. Her appetite should pick up again about week 4-5. If she continues to be picky, give her whatever she will eat that is healthy and safe for her so that the puppies can grow well. Good luck!

    • I have a black mouth cur who is due in 5 days. She was very picky eating I hardly saw her at the food bowl. Now she’s a pig she will eat anything last night she was eating grapes towards the end like the last 2 weeks they become a pig and will eat anything

      • Grapes and raisins can cause acute kidney failure in dogs and cats! Please do not give your dogs grapes you could risk their life. Hope puppys were OK.

  15. We tried mating our Jack Russell bitch on day 9 of her heat. She was receptive and intercourse took place but they did not tie. We retried every two days – intercourse always took place but no tying. On day 20 they mated and tied. For working out a potential whelping date do we go from the first time they mated even though they didn’t tie or from the one time they tied?

  16. My soon to be 3 yr old pitbull is supposed to be due on Sept 25th. I noticed she has been panting but not heavily. She is just laying down and taking deep breaths infrom time to time. I took her temperature and she is at 98.0 c. Do you think im over thinking things or could she be going into labor soon?

  17. My dog tied for aboit 6 times but ony lasted a few mins she has signs of pregnacy but hasnt put a lot of weight on her nipples have changed .

  18. I have an American straffordshire she’s in her 5th week pregnancy my problem is that she sleeps with us in our bedroom, now I see the problem where I can leave her when she have pups. We have a big garden with a very big room that is good for her and her puppies I’m thinking to put her there but I’m feeling worried not to be inside the house. Does this make a difference for my girl please? Thank you

Ive been keeping up with her like if i was prgnant lol my only thing is i need advice with her puppies. Ive been told and have read that if the pups die at any point its normally during and a month after birth. Like when we have babies we take precautions to avoid SIDS how can I avoid it for my Hopes puppies?

  20. I want to start a dog shelter here in Nigeria because people who can’t keep their dogs will usually bring them to me because they know I keep dogs here in Kaduna state,Zaria in G.R.A and sometimes I reject them because of limited resource thought sometimes I feel for those dogs because the owners are probably moving out of town due to transfer from work.I once checked on a gsd,the owner traveled for lot of days and I met the dog already dead on chain at his backyard I was pissed but you can’t report such things here in Nigeria because nobody would care.please who can I contact to get sponsor or adivece on how to go.

  21. Hello, my two huskies bred which is fine I wanted it but with all the reading I’ve done it says she won’t ovulate till around day 11 of her cycle. I also read she most likely won’t allow breeding to occur until day 9 or later, but as soon as she started to bleed she allowed the male to mate with her. Even now a week later she’s still allowing him. My question is which matings would be most accurate to use in finding out when the puppies will be due and when day 50 will be so I can book the x-ray to count the puppies?

  22. Please , I need help. My King German Shepherd has gotten our 11 yrs old Golden Retriever, who has never had puppies, pregnant. We are looking for the signs that. She is pregnant. We are now on day32 . when are wr able to see the difference in her apperance? I am nervous for her, being her first and her age, not to mention his size

    • Hello, I’m curious as to how things turned out for your Golden Retriever? I have a Golden Retriever/Collie mix. Shes 9 1/2 yrs. My Husky/German Shepherd mix puppy got her pregnant. I’m so worried… How did the puppies make out? How is momma?

  23. Have a 8 week pregnant Dobermann due the 18th December . Can they go into early labour with first litter she is carrying at least 10 pups

  24. I cannot believe the amount of people on this thread that have allowed their dogs to get pregnant and have absolutely no idea about the process or what they should be doing. Your dogs are your family! Please do all your reading before you mate your animals, if in doubt go to a vet. If you cannot afford a vet DONT let your pet get pregnant!
    My shitzoo is nearing the end of her pregnancy, I waited till she was 3 years old, I selected a beautiful gentle dog for her to mate with and stayed with her throughout the mating process. It can be very scary for the females. I know what to expect and when to expect it, because I read up asked other breeders and consulted my vet.
    I am so sad for dogs that get pregnant on their first season, who have owners who want to put them outside when they normally sleep on their bed, who have no idea that their dog may not be able to give birth without medical intervention.
    Sometimes all people see is money!
    Our jester will have one litter, then be spayed. She is our baby, but has a right to have her own babies.
    Please consider your pets and your circumstances fully before mating your animals.

    • I so agree with every word you said…Everyone should know about their pups, mating, pregnancy and birthing prior to pregnancy. Funds should be available for your pup and not be worrisome. I had three females in heat, they are my babies, and if you cannot watch your dog during heat, you not properly caring for your pup. Be responsible as she says. You love them, show them you love them. Take proper care please of your loved pets.

    • It’s Shih Tzu. Not Shitzoo. 😒
