i have a 7 month old papillon puppy and she is still not house broken yet, i have heard papillons are difficult to train, but she goes places in the house and does her buissness and sometimes we dont catch her doing it. im really trying to pay attention so i can train her to go outside though,
i was wondering though how old is too old to house breaking a dog??
Ok this is the harsh method and as I can see you you probably wouldn’t want to do this but crate training her is a good way to keep her in her own bed.
Dogs usually don;t soil their sleeping space (although mine did when he was younger).
Another great way, which I approve of and it really works awesome, is to have her attached to your hip.
Put a leash on her and have her everywhere you go in the house.
You can;t leave her out of sight even if she tries to sneak away to do her buissness 
She doesn’t get a chance to do it secretly.
If she still has an accident or she is getting ready to so do,
pick her up and bring her real quick outside.
Praise praise praise, when she does it outside!!
Ignor when she does have an accident in the house, or say a frim (don’t yell) "no"
good luck!
