Having grown up with dogs - always rescued - never bought - a few different breeds including Tibetan mastiff (sick didn't make it beyond 2 years), Gaddis (himalayan sheep dogs - I am from Uttarakhand), labs etc etc, I have to say there are massive advantages to a mutt/indie/pie/pariah/street/desi dog - Indian dogs from any state.
1 - They have the best immunity for our country's conditions.
2 - A well trained Indie is as good as a well trained many other dogs - I can't train my dogs for nothing - however my dad was a great dog trainer.
3 - They are very versatile and can survive almost anywhere in the country - negative temps or high.
4 - They are great apartment dogs and great farm house dogs. They do not smell as bad as a few of these other breeds.
5 - They are extremely good natured, but can be great guard dogs - if you train them to be.
6 - Easy fur management - compared to some other.
7 - Almost any VET even in the remotest part of the country understands these dog's physiology and issues very well.
8 - They develop the least amount of issues. I have a 15 year old in Delhi (called Mamba) and though he is losing his eye sight and hearing, he still runs around, guards his territory, hunts pigeons. Picked him up with no chance of survival - 15 years on - he is refusing to pass on the torch
9 - I have a rescued Himalayan sheep dog (Called Jhabroo) with me in Goa - another one who we picked up with no chance of survival - though meant to be in low temps - he has accepted the heat and humidity of Goa very well, 4 years old and took him only 1 year to adjust. He guards the house ferociously, and greets the guests like they are his. Untrained - just intelligent.
10 - Another mutt we have (called Mitti) with me in Goa, who adopted us - on her own - as a 1 month old pup, tried to give her away, but Jhabroo and Mitti were in love, they adopted each other - both neutered, the relationship is beautiful. A great team - Mitti the alarm module and Jhabroo the spiky aggressive protection.
Like I said I have had multiple dogs, always had dogs, never without one, cause there was always one to save - the street dogs have the best immunity, great resistance against local pests, least amount of issues as they grow old and inbreeding is not a concern. They are fit, healthy, extremely intelligent and a well trained indie is a great dog to have.
