Hey, so lately I've noticed that my dog has been very clingy lately -- always following me around or hiding under/behind furnitures. Here's an example: Now usually my pets don't do this unless there was a loud thunderstorm, but it's clearly a beautiful day outside and she's usually not the one to be timid during thunderstorms. Her companion, another dog, is the timid one. Is it just old age? She's gotten more affectionate/clingy (which I'm totally cool with)? Is there something loud going on that I just can't hear but she can? Or is it something else? Is it normal for dogs to act this way for days even when there's no obvious reason? I'm sure it's not related, but this started a little after our cat died. Would a loss of another animal in the house have an affect on a pet's behavior like this? Thoughts?
