"She was animal-mad and has spent the past couple of years doing absolutely everything with him."
To add to Kate's bad luck, she fell from a horse yesterday and was taken to Tauranga Hospital with a suspected broken pelvis.
Mrs Purchase said as soon as they knew Ash had fallen from the ute, they turned around to look for him.
"He has either been picked up or he bolted off," she said.
Mrs Purchase said Ash was a border collie and is very obedient but could be timid around strangers.
The family is willing to offer a reward for Ash's safe return.
If you have seen Ash or know where he is call 0800 253 253.
