I know of lady who gave human birth control pills to her dog so it doesn't get pregnant and she said it worked.

I still think neutering is more aesthetically pleasing. I don't like to see dog nuts swingin' and swayin'.

why are you looking at that anyway!
wondering about you're cat av now hmmm....

i can here dogs around the world howling and yelping with glee!

no male wants anyone bothering his jewels.
AHEM! so to speak

I say develop birth control for men before developing it for dogs!

I still would advocate neutering and spaying companion animals.
Sure, your male dog might not father any pups, but he'll still be more aggressive and will mark all OVER your house AND have a higher tendency to wander.
And your female will still go into heat regularly, the males in the neighborhood will still circle your house, and she can still develop mammary cancer later in life.

breaking it down:
vomit kitty no like dog balls

I can see this as an alternative for breeders who don't want their animals breeding every heat, but certainly not for the average consumer.

Finally! No longer will I have to pull out just when it's getting good!

i didn't know a dog could do that!

when i was a kid we had a lot of dogs. so we seen a lot of well dogcore(if you will).

so this dog from up the street was all over our girl dog and us bieng mean and vengeful little kids we started throwing stuff at them.

the male dog lost his balance and if you don't know that thier member swells when its in there,you do now.

the male dog fell on all fours facing south and our dog was facing north(it kinda looked like catdog of nickeledeon)
so while they were stuck bottom to bottom the male dog starts yelping from the pain, which in turn made our dog drag him up the alley.

the finally broke loose from each other and i've never seen a dog run so fast
