  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….

    • 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?

  4. Toni Southerland

  6. HI my 10 monthold chihuahua has gotten pregnant on her first heat even though we tried to take every precaution for them not to get together it seems that they must have at some point done this….I’m absolutely worried sick about it all….I was going to mate them just not yet…will she survive the birth this young ?I just don’t know what to do for the best all I care about is her being ok….please please help me because I’m in such a state about it all xx

    • 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.

  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.

  12. I have a poodle and she’s like four years old and she’s pregnant she got pregnant June 15 2018 when is she do

  13. Hi, I have 2 and half year old mix breed wrott and Boer, I crossed her 30th of may and repeated it 5th June but in my calculation I think she have to be due either 30th July or 5th August but up til now know sign of whelping but I can see the belly is big I checked her breast and there is milk. Am confused. Today is 9th August. What do I do

  14. Shihzu mated 7-4-18 I’m feeling babies move her due date seems to far away with all that movement

  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

  19. I have my Hope (Pit mix??) Shes due between Nov.11th and Nov.15th we saved her so im not sure if shes had pups b4 but shes HUGE. Shes been the spoiled baby. 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.
