Come to huahin on holiday and find accommodations for you and your animals. Do your research how to move your animals . Sell and leave everything in Canada cos you will be able to get everything here you need. Otherwise don't worry about anything. I guess you have solved your visa requirements. If you are planning to move to the countryside you can pm me
I could sell you some nice land( nearly 4 rai). But otherwise I am no help for you :( . However I would sell everything and only bring a small suitcase. Your case seems complicated enough, so why bother about your belongings. I could understand that you would like to bring your dog. Can't imagine that it would be very expensive if he comes with you. I don't think you will find a supplier of hempcrete here, but if you can mix it yourself there has just opened a big hemp farm near us.
