<human>: So me and my GF got a Papillon about a month and a half ago (December 28th). He turned 3 months old on February 4th. He seems to be doing fairly well at everything we tell him to do and learns fast. However, the peeing when we are AT HOME is the biggest issue.

We both work 9-5 and we work quite far away so we can't go home during lunch to walk him outside. Thus, we have trained him to use the pee pads as he can't hold it for that long yet. He poops directly on them, regardless if we are home or not. That is not an issue at all. He also goes and pees on them whenever we are not home as usually I'll see 3-5 either wet spots or yellow stains when I get home. 

It is when we get home is the biggest problem. He will pee blatantly right in front of you on the carpet and then go hide under the dining table or the bed. It seems like he understands that he did something we will not be happy about. We usually point at the pee spot and tell him NO. It's pretty funny how he avoids eye contact and makes this guilty face. 

We live in an apartment so we don't have a doggy door and he doesn't really give us signs when he has to go pee. He sniffs for a few seconds, squats down (doesn't raise the leg yet) and does his business even if me or my GF are standing inches away from him. Perhaps he sees us cleaning it up after he does it so he maybe thinks that it's ok to pee anywhere when we're home and that we'll clean it up? He does wonder to the pee pads on occasion as well and takes a leak there from time to time when we are home, so he knows where to go...

Can you succinctly summarize the text in 1-3 sentences?
<bot>: 3 mo old Papillon pees only on pee pads when we're not home, easily takes a piss right in front of us on the carpet when we are home. Any suggestions on what to do?
