Foster home needed for Biscuit, a gentle retriever, for 4 weeks

I'm going into hospital for surgery on Friday, for about 4 weeks, and I have no family nearby to look after Biscuit, my nine-year-old retriever. Biscuit is gentle, house-trained, good with children and other animals. I'm looking for a temporary foster within Bristol. I'll provide food, bedding and medication, and cover the vet costs. Biscuit is vaccinated, neutered and microchipped. I'd love to share regular updates and photos, and I'd love to pay it forward by volunteering at the shelter when I'm better. Thanks for being kind about this.
