I have a 1 yr old border collie that is house trained and he keeps pooping in the house, he does thiis after comingin from outside. He is house broken and he has never acted like this before. Why is this?

Like Eric, I have a dog that used to be housetrained who has begun to poop in his crate at night! I know the mantra of excercise, discipline and affection and I'm pretty sure (?) I give him all three on a regular basis. Tony is a six month old yorkie terrier. I was surprised that he was so easy to train. I put him in a crate the first night he came home and he seemed to like it. When he was three months old he was already asking to go outside to poop. He pees indoors when he's excited but he often peed outside as well. Never did he use to soil his crate. About 3 weeks ago he began to pee in his crate. I made his space smaller. I think he hates his crate now and I can't figure out why. The last two nights he has pooped in his crate and he began doing this about 2 weeks ago. He has done this 6 times by now! I know it must be something I'm doing wrong. I haven't changed his schedule, food or sorroundings. What's going on?? I've googled this and it doesn't seem to be very common. I took him to the vet, but he has no worms or anything wrong... help!

how many times do you feed your dog julie? that could be contributing to it.. a dogs digestive system is efficient enough that its wise not to feed them more than twice a day for a small size. overfeeding may be the prob .. ive had it happen to me..but since i cut back on the feeding schedule of mine i don't have that issue at all. i also give my dogs treats where they would otherwise be fed a meal (but not too many)... there may also be something thats around that may be upsetting Tony... Yorkies are high strung to begin with and as i have a high strung dog of my own.... i know all to painfully well about those foibles..XP my little girl as done that to me too and shes not even a yorkie. when theyre overly upset over something the can pull stuff like that... after all they Are more like eternal children..XP mind you both my dogs sleep with me as well.. could it be that tony wants to hang with you even at night? if you trust him you could use the crate for discipline and travel.. and then leave him out and hanging with you at night. if hes insisting on sleeping with you .. he'll pull almost anything to get his way ,up to and including messing in his crate.. perhaps hes come to resent being away from you for overnight..?
overly possesive animals will try almost anything to keep you with them.. ( i hav a cat with this problem.. but i accept it and grin and bear it ) it might be an idea to try different ways .. but keep your options open.. be firm..but try to be fair.. yorkies have always been known to be very overly sensitive and overreact to EVERYTHING that is new.. i do hope this helps.. i did a similar thing when my little girl started in with me on that.. now she sleeps with me and is no longer messing in my house..lol just make sure to dog-proof your place first and any non chewable things are removed
out of reach .. make sure he understand whats his to have and chew and what isn't .. they ARE really smart no matter what the size. they also understand us a lot better than they let on XD
just because someone can't speak a certain language doesn't mean they can't understand what is being said.. i have it on two good furry athorities that they understand perfectly what we say...(i'm usually quietly observing my dogs reactions to me and what i'm saying. and their responses are remarkable i find .. and amusing.XP)

I will admit that my new yorkie is the dominant force in my house...but I did manage to put her Humping behavior to use. Look for Gidget in the upcoming Sex and the City movie and Kim Cattrall's dog : )
