Yes as long as the male dog is not fixed
around six and nine months
Male cats do not go into heat like female cats do. Female cats go into heat to attract male cats for mating, while male cats are always ready to mate when a female cat is in heat.
Well the loin head male has rings around his eyes and longer fins than the female. The female will often have more variety of colour on her body but generally the male will look more stunning with his longer fins!! Hope this helps :)
the female lives longer
Male dogs don't go into heat they can mate with a female at anytime.Usually they sexually mature around 6 months.

No, female sperm do not have a longer lifespan compared to male sperm.
No. Only a male can impregnate a female. No female mammal of any species can get another female pregnant. For mammals that have a "heat" cycle, being in "heat" is required for pregnancy by a male. If such a mammal (a dog for instance) is not in heat or doesn't have a male partner, pregnancy is not possible.
Male ferrets (and mammals) don't really ever go into heat seeing as they don't have a uterus and can't go through their menses. However, male ferrets will become more aggressive when around a female in heat. Especially when that female is another ferret.

Male cats do not go into heat like female cats do. Female cats go into heat to attract male cats for mating and reproduction. Male cats are always ready to mate and do not have a specific heat cycle.
When the female is ready the male will know.
