It is probably a well-known fact that dogs are not allowed in the heaven (Swarga). For e.g. the dog which accompanied Yudhishthira on his way to the heavens was denied entry in there.
The Smritis also say that gods and manes do not accept offerings of those persons who keep dogs.
But, on the other hand, a dog has a clear cut spiritual connection. For example, it is related to Ketu (which is considered as Moksha Karaka-the reason that triggers Moksha/liberation). A black colored dog is also related to Dharma-related deities like Yama and Shani apart from being the Vahana of Lord Bhairava too.
So, obviously dogs are of some spiritual significance and it is allowed in particular in Bhairava Loka.
- I am specifically looking for references which talk about as to whether dogs are allowed in Kailasha and Vaikuntha or not.
