There is no such breed. Each female dog as an individual will vary during her heat. Normally you see the most blood in the beginning of the heat then it slowly stops.
Yes. Females do bleed when they are in heat. I would suggest keeping them in a linoleumed or tiled area to make cleaning up after your pet easier. You can also purchase "doggy diapers" for this specific purpose.
No, they get pregnant about 3or4 days into the bleed
I called the vet and the answer is 3 weeks.
They bleed for about 3 weeks while in heat.
air block in heater hose most likely bleed it
No, there is usually no bleeding involved while the guinea pig is in heat.
no, dogs can only breed while their in heat. they're gestation period is around 2 months
six to eight months
no guinea pigs do not bleed when on heat but if your guinea pig starts to bleed it means it needs worming
Yes, they do, eventually. If you breed a mare in June, her heat cycle will most likely be missed in July, if she got pregnant. There have been some reports that a mares heat cycle will be missed twice, but there are some studies still going on.
More than likely an airlock in the cooling system, bleed the system and should be fixed.
This is normal - not all dogs spot or bleed during their heat cycle.
