What is wrong!?

Is he the dog that's on the steroid medication?  I'd double check with the vet to make sure what's going on might not be due to them. 

Otherwise, I'd find a way to keep him confined so that he doesn't have to deal with the rest of the family.  Especially, for right now when he's not feeling his best and you are having issues with him. 

No. Pedro isn't on any medications, Chico is the one who is taking them.

Red ... pick him up and set him on the bed or somewhere you can really look at him.  Lift his upper lip and look at his gums.  Are they nice and pink as they should be?  If white that is literally a vet emergency.

The other thing to do is press the tip of your finger on his gum pretty firmly for maybe 10 seconds ... let go and the gum should snap back to 'pink' right away.  Both of those can be signs of internal bleeding.

Very carefully touch him gently all over.  Make sure he is putting weight on all 4 legs.  Carefully touch his belly, all over his legs, back and chest.  Do you get any reaction or reluctance to let you touch him anywhere?

My point is -- look him over really well to make sure he didn't get seriously injured.

Then honestly -- while you have houseguests like this, go and buy 3 small crates and crate them IN YOUR ROOM while you are gone.  (lock your door if you have to -- but they shouldn't bother with the dogs if you aren't there.)

You can leave radio/tv on while you're gone.  Crating is not cruel -- and I think it's Chico who is a bit afraid of the crate, so if you crate the other two you can leave him out of the crate but IN your room with the door shut.  He may not be terribly happy but it's easier than him getting hurt or plagued to death.  (and frankly this may be part of your answer about why he's been so ill-tempered lately)

there are times when you gotta do what you gotta do in order to keep them safe.  If this won't work for some reason then figure out what you CAN do to keep the dogs out of everyone's way.  Just saying "you shouldn't do that" isn't going to work (particularly if you are the obvious one who treats the dogs 'better' and no one else cares as much as you do).

It's too hard for Mom to make sure they stay out of everyone's way (even if she claims she'd be glad to do it) -- when you have a volatile situation like that sometimes you just plain have to take things into your own hand and MAKE SURE no one can get to your dogs.

I agree, if he does not come out of this in a short time, take him to the vet.

I've looked him over, but not REALLY checked him over. I will do that as soon as I post this.

Our vets aren't open this late though, and even if you call the Emergency line, they will tell you what they *think* is wrong and what they *think* you should do. Even when my uncle's dog got in a really bad dog fight and was gushing blood, they were told they had to wait until the morning. If he is sick tomorrow, or feeling the same.. I'm taking him to the vet. ANY vet.

He was gushing blood and they couldn't see a vet that night?  That's unreal.

Just thought of something that could be related to this.

Pedro didn't eat at all yesterday and then today they said he was like this. Could he be diabetic? I'll have to check out the symptoms but as soon as he ate, my mom said he stopped shaking. (I was gone for a bit)

Now he's acting okay, but very tired. You can tell he doesn't feel well. He's still not wrestling around, playing, ect.]

*Nvm, none of the symptoms related to being diabetic. Maybe it's something else. Man, this is making me worry..

I've read on here that little dogs do get hyperglycemia--low blood sugar-if they go too long without food.  I'm not too versed in it but I think I've got my facts straight.  Did you ask your mom if anything happened with him while you were gone?  I always ask my husband how Willow was when I get home so I get a full report of her behavior, etc.  Maybe something did happen with the family??  Did someone feed him something that isn't agreeing with him??

Do his ears look red inside? Maybe it's an ear infection bothering him.  Quite a few of the chi's I know get them pretty often.

 I think that he probably should be seen by a vet.  Hope it works out for the little guy.

His ears aren't red, his gums look good. (They aren't pink, but aren't white. ..sort of a dark pink with some brown spots.) I softly felt all over his body, everything seems fine.. nothing seems like it's hurting him.

He's still shaking badly. Quits sometimes, but then starts again. Still acting afraid of everyone and everything..

I'm keeping a very close eye on him all night. Tomorrow if he isn't acting any better, off to the vet he goes. I don't care if I go in debt, as long as they figure out what is wrong.

Yeah, I think it's best to bring him to the vet.  It could be any number of things from not serious to very serious.  He could be running a fever and that could be causing the shaking too. 

Could easily be pain ... a pain response often looks like 'fear' because it's inate (when you're in pain you ARE vulnerable).  But yeah -- definitely to the vet. 

I tried to get him to eat yesterday, but he wouldn't.

Do you think he could be under tons of stress? http://www.wagntrain.com/BodyLanguage2.htm

As of now, he's laying down in my lap.. calmly. He's doing fine. When people come near me he starts shaking. Maybe all these people in the house are making it hard on him? What should I do?

* tail between legs

*ears down

* lowered body

* licking air

I thought of taking him to my aunt's house tomorrow when I go to work.. but I'm worried that will stress him out more. He absolutely loves her though, she had him and then gave him to me.. but just being in a new place and mom's (I'm) not around, maybe it would make matters worse? I know leaving him here while I work (7:30am - 5pm) isn't a good idea either.
