This makes 6th litter! She keeps letting her!?

Relax. Take solace in the knowledge that there is nothing that you can do. If your sister was open to the idea of having the pet as a companion and not a money-maker, she wouldn't have opted to mate her so much or to mate her pups. As far as Mercedes health, again there is nothing you can do. Eventually nature really will take its course. At some point, though, Mercedes will cease to conceive. Maybe your sister will keep her still, but if not, you can always adopt her and give her a comfortable life. Worry about the things you can control. I'm sorry. I know what a difficult position this is to be in.

Luck. That's why she's alive. Puppymill dogs often endure the same, in worse conditions....by the time they're 5, maybe 6, they're done for. The pups may all have survived, but how many will be surrendered to shelters or end up in bad homes?

Sorry, but your sister is ignorant. Maybe explain to her that there's nothing "natural" about a Chihuahua. Dogs are not part of nature; they were created by man, through selective breeding NOT natural selection. We are supposed to use responsible animal husbandry techniques to ensure the health and viability of all our domesticated animals.

So your sister using the dog like she's a rapid-fire puppy shooting uterus is not "nature"....it's your sister being an irresponsible sleazebag.

Is your sister having a baby every year? Why not? Isn't that "nature" for our bodies?? What a screwed up mentality. God, the thought of someone with that mentality making more humans is mortifying.....hopefully she's NOT spitting out children....*shudder*

She's letting brother and sister dogs MATE? WOW. Fantastic pups she's producing. I hope when she puts an add in the paper she mentions that they're products of incest and will have a slew of health and temperment issues....

Your sister is extremely irresponsible.

All you can do is beg,

but she will be fine lots of dogs have lots of

litters like all those breeders out there

as long as she doesnt keep her or the pups in

a kennel then its not too bad.

Some people just can't be changed ... that poor dog. Maybe you can direct her to this website: http://www.learntobreed.com/

Your sister needs to get this poor dog spayed before she dies - doesn't she understand this??

Hasn't her vet told her - she does use a vet?

While you are at it, try to talk your sister into getting spayed too - enough selfish idiots int he world, along with enough dogs.

Unfortunately, you can't fix stupid.

Poor dog.....

Can chihuahuas have five puppies...?
