Yes they do.
Dogs don't have souls like you and me. When they die they are reincarnated into something else in a part of nature. At least that's what I was taught.
That's just a concept made from western society since we tend to care more about dogs than our own damn species!
Is there really any place like heaven?
All animals go to heaven except humans
Are you brainwashed There is no dog or cat heaven That is so made up it makes it funny
Heaven does not exist, so dogs cannot go there. Neither can humans, and we should be glad of that.
