A dogs heat cycle will last three weeks or so. The most obvious sign is that they bleed, however some dogs clean themselves so well, you will never notice this. Other then bleeding, you may see a change in behaviour, she may become more submissive to the male, she may allow him to mount when she doesn't usually. Unless you intend to breed, for the health of the dogs (not to mention the pet population) you should have them fixed and then you can avoid this problem alltogether.
it bleeds its privet swells and it bleeds
It must be scared, in heat,pregnent,or trying to protect something.
female chihuahua's leak drainage from theyre cooter's and will hump things
He is probably trying to mount her and she is not ready to mate. The female will only mate at a certain time of her heat, when she is ready she will flag him and flirt with him to let him know she is ready and willing during this time will be the only time she will allow him to completely mount and she will stand for him.
no he is not \
Yes, as long as the chihuahua is "in heat" and they get "hung" (which you will know), the pug can get the chihuahua pregnant.
a male chihuahua will mate with a female chihuahua when she is in heat (AKA ovulating, on her period) they can sense it and then have the urge to mate.
Dogs lick themselves just as cats do, to clean. It's possible that the dog might have a skin irritation or something.
this is a sign that your female dog (bitch) is on heat and is trying to get the male dogs attention.
insolation keeps heat in best.
I think the main animals that live there are foxes.
About 7 to 10 days.
