Pet Partners owner Deb Bodger said she offered a boutique service and catered for up to four dogs a day at her house, at $35 per day. She was booked out. "It's just growing and growing and growing," she said.
The company had taken on nine partners in Papamoa, Mount Maunganui and Tauranga, although not all of them did "in-home care".
"Nowadays pets are considered an integral part of the family and their physical and emotional wellbeing is important to people. Often owners can't be there to do that, because they are out earning a living, but they want the best for their dogs because they love them with all their heart.
"We can create environments to suit all types of dogs. People have commented about similarities to home child care and it's not dissimilar at all, actually. The dogs are stimulated mentally, emotionally and physically in a positive caring way."
Dog owner Anna Zandstra said she had no qualms about paying $23 a day for Millie to attend doggy daycare at Absolutely Paws, for 2-4 days a week. "Millie has been going since she was a puppy and the staff genuinely love the dogs. After work it is just like picking up a child from daycare."
