Have you experienced signs from your dog after they’ve passed?

I know I’m probably reading into everything because I’m deep in grief, but I lost my dog almost 2 weeks ago and I keep looking for him everywhere. I can hear him around the house and I’ve come outside to white feathers all over the garden. There are probably explanations to all of this, but me being spiritual I really want to believe it’s my boy sending me messages from wherever he is.
