ah lately so many people buy maltese.... i also start to search for 1 d.... like after many years being in love with them.... but very hard to find female puppy....

For a 3 months old puppy, every 6 times miss 1 or 2 times, your dog is doing great already! Even a 3 months old human baby yet to learn how to go toilet on her own, I would say your puppy is very smart boy. Continue praising while he is doing the right thing will encourage him to aim accurately. Do expect accidents or nottiness sometimes, it is understandable as they are animals anyway.

Also, have you tried changing the pad more frequently or placing 2 pcs of pads instead of one? Some dogs tend to refuse to pee on the pad when it is full or almost full especially those hygienic ones. Believe me most dogs do love to stay clean!

I can't give u the right answer because my kids are both girls xD so honestly what I'm gonna say is based on the readings that I read when I do my research 

as far as I know, some dogs will do marking when u bring them outside or play that has others dog's smell or pee xD but there is also some case like yours, mark in the house xD for this, u gotta wait White Palace  to help u answer xDD

but for pee with one leg up, I got read before somewhere that say if ur dog start to do marking, some will also start to pee with one leg up
Of course cannot xDD
their nails is thick n big not like our nails la..

this is a reward to your dog when he is doing right things. Since this is training period, you should continue to reward him until you feel that he is confirm and know where to pee n poo then you can reduce the treat and praise him by voice or physical touch.
When reward him a treat doesn't mean that you need to feed him a lot...just a bit is enough

This is my adv and you may use it as reference.

i bring my girl to gasing vet thou its far but I'm satisfied with the vet there

I don;t know the exact address but if not mistaken someone got posted bout it at poodle thread recently. Will go there n find for u the exact add

Sorry just got back to kl =]

Last time when I bring autumn for her 2nd Jab, they charge me RM 35 for the vaccine

cute!! 

if i tie up my touffy hair like tis his will keep scratching until he get rid of the rubber band... 

How i wish my Cookie lets me tie her hair too!! She's just one week older than Kaka!

Like Touffy she will keep on scratching at the rubber band until it drops off! 
ETA: This is her pissed off face when you tie up her hair! 

that is stomach acid...
my touffy oso used to vomit those yellowish liquid sometimes. 
i asked vet, she said small breed dog easier to hav stomach problem
coz they eat lesser and stomach tends to empty faster than big dog.
coz last time i feed touffy twice a day about 3 table spoon per meal.
mayb tat is not enuf. so now i put 6 table spoon in his bowl.
he wldnt finished it all at once...
he oni eat wat he need.
so now no more vomit edy... 

For the yellow thing, make sure bring to vet to check just to be double safe.

Licking private parts is natural as part of their 'self-cleaning'. Just dont let them lick until so shiok / too much coz thats where they can transfer germs / bacteria from mouth to down there. If you see some infections, can apply some antiseptic cream, but pls dont use a lot, little bit nuff liao.
