Can a female dog get pregnant from only one dog or more at a time?

Answer 1

For the person that asked the question:

Yes, there can be more than 1 sire, most definitely.

Ever look at a litter of kittens whose 'Mom' ran the streets and you were surprised at all the colors and types of coats ?

A female can get pregnant/bred by several dogs. This is why breeders are extremely careful about separating the b+tch from any male.

A b*tch ovalates and the eggs drop. They go down the 2 horns of the uterus to the walls that supply nutrients.

Here's how the mix can occur.

Let's set up a scenario...... The b*tch accepts a male early for some reason. The owner is keeping the b*tch separate from the males and didn't know about the first breeding. This was on day 10.

Well, the sperm can last 5 days, maybe more. During this time, the boys are sitting there on the 'ready' so to speak.

The owner breeds the b*tch on day 11 and 13 and the sperm from this fellow are in the mix.

However, on day 14, the b*tch escapes and even though she is found missing an hour later, another male has climbed under the fence and after his breeding, he hears the owner yelling and runs back off (or the owner may even see them in the same yard).

What will the dam produce ?

So, pretend you've got one of those pinball games with the cups that catch a few balls and the others go to the bottom. You have 12 cups representing the 12 eggs waiting.

Put in 10 green ones for the 1st male dog, 10 pink ones for the 2nd male, and 5 blue ones for the 3rd male. (25 sperm, 12 cups to hit)

Give the board to 5 different kids to play 1 gave each until all 12 cups fill.

Take count of each. So, what did you get ? Like tossing dice.

Since the b*tch adds in her genes, it's impossible to tell which pup may have a stronger influence from her. She may be brown with white legs, chest, and a blaze; her dam was brown with white legs, but her sire was white.

On top of that, pretend 2 of the males were white, and they had 1 grandsire and granddam in common. The other male dog is brown, but his dam was white.

This would be like shaking a snow globe !!!! A flurry of genes!

It is impossible to tell which puppy was sired by which male without testing the DNA of the dam, the 3 sires, and all the pups.

I remember one litter I had of 10 puppies. I wanted to keep a female. You've got it...... 9 males and 1 female and the female had a disqualifying mark. " Toss of the dice ! "


If the litter is indeed sired by more than one dog and is going to be registered, then the DNA profile of the dam must be supplied to AKC or UKC as well as those of the sires and the pups.

In other words, it takes both parents information to have some basis on which to exclude a specific sire for a specific pup.

This is going to be very expensive to do the whole litter.

If a person only wants 1 pup registered, then the tests can be sent in on the 2 or 3 sires, the dam and the 1 pup......

WHEW !

As you can see, it is HIGHLY important to keep a b*tch in heat totally locked up with a solid floor and walls, and the male completely in another area. I always make sure there are at least 2 barriers between dog and b*tch. My males are in their kennel building and the girls stay inside the house so I know exactly where they are.

DO not trust crates, especially wire ones...... besides escaping, the dog can severely hurt himself and I've heard of a dog choking after pushing his head through.

DO not trust the interior doors of the house. I know of a chihuahua that tore through the flimsly walls. The b*tch had to get a hormone shot prolonging her heat - - - can you say "Pain in the %#@& ?"

Don't forget that - if an accidental breeding take place, call your vet and get a "morning after" shot. Next SPAY and you won't have to go through all of this - - especially finding good homes for the pups.

FOR DOG PEOPLE, ESPECIALLY DOG SHOW PEOPLE, VETERINARIANS, and VET NURSES OR VET TECHS :

I see some very confusing information from people I've noticed to be knowledgeable. I also agreed with some and know some are not correct.

There's a CVT or CVN and a veterinarian to be that answered, too

I'm learning and hope my information helps others learn. With the conflicting information on this question, however, I must point out that some of you may want to go to seminars with people such as 'Dr. Hutch' ( Robert Hutchinson DVM) of Ohio, Janice Cain, DVM of Bishops Ranch Clinic in California , or trained reproductive specialist veterinarians.

Reproductive specialists are available by phone to your veterinarian for a fee. I don't think Dr. Dodds in CA ever charged anyone...... she is just awesome.






AKC does parental testing:

akc.org

http://www.akc.org/dna/index.cfm

http://mail.ukcdogs.com/ukcweb.nsf/webpa...

The AKC offers a comprehensive set of voluntary and mandatory programs to ensure the integrity of the AKC registry: voluntary DNA Profiling; the Frequently Used Sires requirement; the Fresh-Extended/Frozen Semen requirement; the Multiple-Sired Litter Registration Policy; the Import Breeding Stock requirement; and the Kennel Inspections/Compliance Audit Program.

The AKC has built the world's largest database of canine DNA profiles for parentage verification and genetic identity purposes.

The Science Behind AKC DNA Profiles - -
AKC DNA Profiles are generated using the same technology used by law enforcement agencies throughout the world. How does this work? In humans and dogs alike, each gene is present as two copies (displayed as letters). Offspring receive one copy of each gene from each parent in a random process.

Compliance Audit Program - -
DNA genotyping is one of the tools that AKC Inspectors use during routine kennel inspections.
AKC inspectors review litter and dog records, check dog identification, examine the conditions of the kennel, and collect DNA samples from litters and their sires and/or dams.


UKC tests DNA too !

"CHIC" DNA respository website:
Great breeder information and FAQ's

http://www.caninehealthinfo.org/dnabankfaq.html


DNA testing for parentage is done by *several* companies like this one example:

http://www.vetdnacenter.com/canine-parentage-test.html

Parentage among Canines can be definitively established using PCR technology to compare allele sizes.
DDC Veterinary is using a 16-DNA marker panel for routine parentage testing and keeps an additional 13 markers in reserve for extended testing in cases involving closely related dogs.

Canine sample collection is quick, easy, and painless. Anyone can collect a sample using a buccal swab for collecting cheek cells.

The testing fee is $38 per sample; for example, if a sire, dam and 1 offspring are tested, the total fee is $114. Yep, so a whole litter could be on up to $300 or more.

A typical test includes both parents.
If the dam or sire is missing, please contact the company for more information about testing options.

You will receive a detailed Parentage Report showing matches or non-matches along with a detailed explanation of inclusion or exclusion of a sire. DNA Profile Certificates for individuals can be ordered for an additional $10 per certificate.


Like dog parentage GENETICS ? ? ? ? ?

this page helps explain using the little blocks from results of a gene test example .......

I 've seen people good enough to plot all of this out and work it through a litter until my head felt 'blank!'

Answer 3

A female dog can carry puppies from different males if bred that way. The outcome will vary and there is no way to tell until the puppies are born.

Example: My Boxer was bred to another boxer, two days later a golden retriever jumped the fence and we had 3 boxer full bloods and 2 mixed.

A female dog allowed to roam freely during estrus can end up producing puppies from multiple fathers. Breeders might occasionally breed a female to more than one desirable male for various reasons, in which case the only reliable way to determine parentage of the puppies is through DNA testing of the pups.

Answer 4

A female dog could have up to male dogs as the father. It just depends if all the eggs got fertilized. I knew this one guy who accidentally had his female dog get out and she mated with this other dog....dont kno the breed and she also mated with the intended male which was a lab. The guy didnt know about it till tthey were born and only half of them looked like full blood labs. Later he took them to the vet and did blood test and the ones who looked full blood were from the male lab and the ones that were mixed were from another male. Hope this helped you!

Answer 5

The owner of the dog needs to know how to "operate" the dog, same way you can get into a car that's in perfect running order but if you don't know how to drive you won't have much luck making the car go anywhere. If the owner doesn't know how to maintain the training, the dog will soon become untrained again. Read more here https://tinyurl.im/Rs7Eq

People seem to think that once a dog is trained, that's it. Not true. You must reinforce the dog's training every single day in some way. It's best if the owner and the dog go together to get trained. As a professional trainer once said to me "We can train any dog in 2 days. It takes longer to train the owners

Answer 6

Yes, dogs (and cats) both release many eggs when they ovulate. Thus, each egg could potentially be fertilized by a sperm from a different 'donor'.
It is not that uncommon for dogs or cats to have a litter with two or more fathers. Theoretically, if there were enough males present at the right time, each offspring could have a different father.
Again, theoretically speaking, if a woman released more than one egg, and had more than one partner, she could have twins etc. with different fathers.

Answer 7

Female dogs ovulate during several days in heat. If she ovulates, eggs are fertilized, she's pregnant. If she ovulates again (yes, this happens) a day or two later and a different dog fertilizes the eggs, you guessed it. A batch of pups with two studs.

The last egg to be ovulated, therefore the last to be fertilized, is called the runt. He had 2-3 days less time to grow than the rest, so he's the smallest of the batch.
