I looked at all of Miloh's pictures in your album...........he looks yorkie to me, just on the bigger side. He is also VERY cute!
How old is he right now and how much does he weigh? At 13 weeks you could double his weight now and get an approximation of what he MIGHT weigh as an adult.
You have a chance (up until 6 months of age - maybe) to get his ears to stand..........if you want. They sure look cute floppy too.
To try and get them to stand you will need to keep them shaved to keep the weight of the hair off. Just trimming them a bit will probably not do it. Being a bigger yorkie, you might even have to tape them after they are shaved. I used masking tape; I hear the blue painters tape works well too & comes off easy. You leave the tape on for about 2-3 days then take it off for a day or so and repeat until they remain standing. A puppy teething can cause ears to flop down also. I've got 3 yorkies; my first has floppy ears. That is only because I knew nothing when I bought him and didn't probably didn't even know about ears supposed to be up. So I never taped them. No matter, I love him anyway!
Miloh is adorable! Congratulations on your new family member & welcome to Yorkie Talk.
