My mother has a small dog Chihuahua / Shih Tzu, 6 year old, male, not fixed.
His diet consists of boiled chicken gizzards warmed up in the microwave, turkey sandwich meat, Priority Total Pet care cat food that's in gravy and few cat greats.  He has a CONSTANT supply of food out for him.  He does have a constant bowl of Iams dry dog food out for him that I bought, but of course he wont touch it.

He is VERY aggressive.  It actually seems as if he is trying to create issues by walking of standing right next to your feet.  If you get to close he flip out biting your feet. Sometimes he will even place on foot on top of your foot then either stare at your foot as if he is daring you to move it or he will look up and growl at you.  It you tap you feet lightly on the ground too making times he will go after your feet.  If you pick him up he flips out growling and threaten to bite your hands.  When out side if he gets even slightly tangled in his leash he flips out biting the leash, and spinning in circles.

Freaguenly when he has a bowel movement its seems to be a effort for him and it sticks to his ass and tail. He does get hair cuts, he doesnt have long hair.  He also has anal gland issues and he is taken to a vet to have them squeezed.

Another bonus is that he pees all over the house.  She continues to place dog pee pads where he finds a new places to pee.  You can take him outside, he will pee all over outside marking his territory, then come inside and pee somewhere as soon as he is not being watched.

After all of that my question is:  Is the diet of organ meat and sandwich screwing him up?  I assume the high fat high sodium diet is causing the bowel movement issue (am I right) also play a part in the aggressiveness?  I'm thinking that if he was fixed it may mellow out the aggressiveness and stop the indoor territory marking.

Any ideas?  My mom thinks that the diet has nothing to do with it.

Any help would be great.  

I'm not a vet but with regards to the pissing everywhere and being aggressive, I've seen dogs calm way down when they get neutered.

Not a vet but the dog is psychotic.

Not a vet.

1) Your mother is an enabler, she is letting the little rat be the master and she is the bitch.
2) That is an awful diet for a dog, of course he wont eat the dry food because of all the crap he is fed.
3) A six year old that is not house trained?? pee pads are not the solution - try good training, a properly cleaned house (especially where the dog has peed), and crating when not able to watch the dog.
4) The dog is aggressive because he thinks he is the boss (alpha), you don't recognize his authority so he tries to put you in your place. When he bites you put him on his back until he stops struggling.

The aggressiveness and urination are from bad training and general domination issues.

Is there a reason she feeds her dog cat food?

Oh, and not a vet. But my wife is going to school to be one.

chihuahuas are a single person dog, in other words only bonds to one person.  It is common for them to be aggressive towards everybody else.  

the sticky crap is due to a poor diet.  IAMS is a very bad food, he needs to be on a strictly dry food diet.  try the website dog food analysis look at the ratings and find out why iams sucks.  buy him a 5 or 6 star food even 3 star food is great for dogs.

"fixing" him now might not "fix" the problem.  neutering a dog makes him wander less and a little more tranquil, but since the dog is 6 years old, I doubt it would make a difference.  

you litterally need to watch the dog whisperer and take the advice, it works wonders, trust me, I have 4 dogs.

Thank you
Im convinced on why there is the issue.  I just need to find a way to convince her.   I dont put up with him.  I will lightly hold his head to the ground when he gets aggressive until he mollows out.  I Havent tried the, put him on his back idea but I like it!

not a vet, but I would recommend throwing him out side and then shooting him. non-working dogs are not worth a second thought when acting this way, in my opinion. if there are other dogs do it in front of them to show them who is boss.

And thats not helpfull and or possible.

And nchapa, thank you so much for that site info.  We don't have a dog as of yet, but when we do I'll be fully researching that site for proper nutrition since up till now I thought IAMS was good food.

sorry you feel that way, just trying to help. honestly, it would solve the problem though.

Your dog thinks he's the boss.
