Huxley, currently asleep under the desk at work, is a rescue from Dalmatian welfare. They have local bods who will come and vet your house, garden and domestic set-up. While he/she is there they will ask if any on the website appeal to you. Once you pass the assessment they arrange for you to collect the dog. Huxley came from Devon, we’re in Suffolk and the handover was at Brentwood after they had relayed across the country.
Bear in mind some breed welfare organisations won’t entertain you if you have no previous experience of the breed (Pointers are one). I wouldn’t recommend using RSPCA as they no longer appear to have lost their way as an animal welfare organisation.
