There are a couple of doggie holiday home franchises near me, based in Lee on Solent and Fareham covering close to your area
We’ve used them several times and it much less stressful on us and the dog leaving her with someone she knows
A week in a family home is around £300 but I don’t know how much goes to the person and the franchiser but it seems pretty lucrative for both
They offer info on setting up your own on their website if you look,
