When you're simultaneously overcome with the desire to occupy your 4 3/4-month old (I never know whether I'm supposed to discuss babies' ages in weeks or months--did I miss that memo while I was busy being all knocked up or struggling with sleep deprivation after the fact?) AND your incessantly energetic Jack Russell Terrier, don't despair. There IS a solution.
Bacon-scented dog bubbles!
Yes, it's true. This exists. Bacon bubble stuff. And the best part is that the 4 3/4-month old will be fascinated by the energetic Jack Russell Terrier as she leaps and twists and bounds and snaps at the bubbles.
It's a happy ending for everyone, really.
