Each animal that has joined our family has brought in a new dynamic, none more so than Bonnie the Pomeranian: a toy-sized dog who, despite her diminutive size, has always been convinced she is at least 50 times larger than her 2.5-kilo weight and barely 18cm to the shoulder.
Over the years, reading about these dogs, it seems that if you catch them really early, you can turn them into a perfect, but helpless, handbag dog. The type of dog that never moves far from its human, or safe place; a dog that sits quietly where it is put and only moves because someone moves it.
In a household already occupied by three dogs, two cats and three humans working full time, when Bonnie joined us at around a year old, she was thrown in at the deep end and, other than keeping an eye on her for the first few days, she was allowed to find her own place in the pack.
Within days she was joining in the rough and tumble between 27-kilo Sassoon and 17-kilo Molly. Wrestling and rolling across the floor with three-kilo feral cat Amber. Facing down queenly cat Jade's hissing rebukes and head butting and teasing grumpy four-kilo toy Yorkie, Jack the Nipper.
The occasional yelp as one of the larger dogs accidentally stepped on her, or Amber caught her with her claws during their mock fights, never seemed to stop her. She just charged back in with more guts than sense.
If she could be trained to sit still for more than a second, she could sit easily on an adult human hand and look like a perfect version of her breed.
Instead she never stops, racing around like a dynamo, keeping up with her larger siblings, on legs no thicker than a chopstick, but a personality as large as an elephant.
Her strangest behavior, however, is something that happens less often in present-day dogs, something we have never heard from any of our other dogs - Bonnie occasionally howls like a wolf.
She is too small to get any volume, but without doubt she is channeling her inner ancestral wolf when she is desperate to get someone, anyone's, attention when something worries her.
In fact her latest howl probably saved elderly Sassoon's life!
