Yes they can actually. Dogs produce multiple eggs(ovums) and one sperm can only fertilize an egg one time. If a dog was bred to two separate dogs within the time of being receptive(in heat), sperm from dog can fertilize one egg, while sperm from the other dog can fertilize another egg.
Yes, it's true that a female cat can mate with several male cats and have a litter of kittens of all colors and that goes for dogs as well.
Yes, Whitestorm mated with Willowpelt and together they had a litter of kits. Whitestorm is also the father of Sorreltail, Sootfur, and Rainwhisker.
No, dogs and cats cannot mate with each other because they are different species with different numbers of chromosomes.
Maybe, depending upon whether or not they have the same father and what breed the dogs are. However, even if the male and female are registered, their offspring cannot be registered. The puppies will have a higher chance of genetic defects, and any further inbreeding would exacerbate this in future generations.
Yes, and they will produce a liger or tigon (ligar if the father was a lion and tigress was the mother, and a tigon if the father was a tiger and mother was a lioness.)
No, both cats and dogs are too genetically different to mate with a fox.
No. Only dogs can mate with dogs.
Any two dogs of the opposite sex can mate, but when they are from the same parents (even if from a different litter) are still considered brothers/sisters. Therefore you would be inbreeding or 'line-breeding'. Inbreeding or 'line-breeding' are not something one should do. You have seen turtles with two heads, or the sheep with five legs... these are results of inbreeding.
Dogs don't marry, they just mate and are rather promiscuous. However, dogs can and do mate with other breeds provided the anatomy is correct.
No, they are different species, like cats and dogs. They will not try to mate, and cannot produce offspring together.
yes you can
they mate like dogs
