There's a pet out there. Just waiting to eat your birthday presents. That would be bad.
Look, we all know you'd forgive your pet. You'd have no choice. You love that pet. But wouldn't it just SUCK to wake up on your birthday and find that all your presents had been eaten? Even if you could laugh about it later.
Help your dog control its animal nature. Put the good stuff on one side and your dog on the other. Set up a pet gate and endure a little bit of whining and you can enjoy a LOT of birthday after.
Which will be good. And it won't end with someone locking someone else into the garage while swearing.
