Dog parents of Grapevine. Looking for suggestions and opinions

I would suggest a mid sized dog over a small one, they tend to have more complications and are vulnerable

Most breeds can be trained well, including indie

I adopted an indie breed in my apartment. Few months were challenging as it was a pup. But once trained, it was smooth. Potty training is must.

Your choices are fine considering you have a 2bhk with balcony.

Dogs are such a lovely creature. Always playful, protector. They sense dangers lurking nearby but this peaks only when they are in their packs. Why do you want to get a single dog and imprison it in a 4 walled building away from other dogs, just so you can get internal gratification of helping a poor animal or may to to fill the empty void in heart. It this right ? You are thinking you are adding family but is that dog feeling same. Keep yourself in shoes of such a evolved intelligent animal. Trapped and surround by other species who give him everything except freedom and no one from his species to communicate.
