Dogs do not have periods. When a bitch goes into heat her teats may become enlarged.
Yes, the female dog's vulva (external genitalia--the vagina is the part inside) will swell, sometimes greatly, as she comes into heat.
Like Females we have are period and female dogs also have there period every six months.But there is called heat not a period it usally last up to 3 weeks.
female dogs can have there preiods as early as 7 months
they have periods but then it is called going into heat
When the female's egg is fertilized.
Hi yes I just found one at www.quinncarlin.ca/store/WhelpingBoxItems.php. now it is called breast pump for female dogs but not sure what it looks like because they have to attached pictures.
Yes with larger dogs there can be a smell.
dogs are actually infertile and dont get there period until after relations
They can be bred when they have their first heat cycle which can be as early as four months but is more typically around six months. It is generally not recommended to breed a dog on it's first heat.
Yes they are allowed if you want pups but if not keeps them on a lead.
It depends mostly on size, usually the biggest issue is the size difference, the way they are going to do it, the base on which they will do it and many other things. The female needs to be the bigger dog because if the male is a great Dane and the female is a chihuahua then the babies would be too large for the female. Other than that issue, yes you can. Just don't try a mix between a Bulldog and a Shitzu... ;) lol Yes you can crossbreed larger dogs and smaller dogs and as it has been said, the female has to be bigger or else the puppies will be too big for her body to hold. The female has to be bigger and you better not be trying to make the dogs breed because if you are you will get punished someday. Thank you.
Consult your vet. You could expose puppies to rabies when in womb and not fully developed and when breast feeding from mother. Less of a threat when dogs are bigger, tougher breeds.
She will no longer have a period because when she gets spayed all the vet is doing is taking out her reproductive organs
