Esta- I don't think there is a "right or wrong" answer to your question. It depends on your dog or dogs, and their temperament. It also depends on the care they will receive at home versus the care they will receive at a kennel.
I have done both. My older laid back dogs were fine at home with a caretaker coming in 2-3 times per day. As they aged and became more stressed at being left home alone, I found they did better in a kennel. It seemed as if being at home alone was stressfull-in a kennel situation they had enough attention and distractions to occupy they. I visited and researched the "local" kennels and at that time the one I would trust with my dogs was and hour away, but worth it. When I got my first Berner, we had planned a vacation beforehand, and so I found a friend who would stay in my house with a 4 month old puppy. As the time approached, and I began to understand my puppy, I realized that I would be more relaxed with him in the kennel of my choice than at home with someone who, although they loved dogs, did not have the experience with Berner type dogs that I wanted. I was more comfortable with him at the kennel. He did well and I enjoyed my vacation. I have had 3 Berners (only 3, I know.....). All very dog and people social. Leaving them at home with a live in trusted person (my children or a Berner sitter I know) is preferrable. But, I'd rather have them in a kennel then home alone with someone coming in 3 times a day. They would be lonely, as they are used to a lot of human companionship. I am fortunate to now have a nearby kennel that offers play time, and lots of TLC. I have never had a bad kennel experience with my dogs. Again, you need to research the kennel. I also feel that the kennel experience may help with the stress of having to leave ones dog at the vet if necessary. Maybe it's just another part of socialization???
