Dogs that bark constantly do tend to be tiresome and Amazon supply a range of products that can help reduce this problem. Before you go out and buy any dog behaviour modification device we do suggest you discuss this with a dog trainer or behaviourist first. We do not recommend any products that involve electrical shocks - these are not suitable in our opinion for people who love dogs. Other products may help, however the best solution is to take your dog to a dog training class and learn along with your dog what is suitable behaviour. Dog training classes are for dogs (and people) of all ages.
If you are not sure where you can find a dog training class them simply phone your vet and ask, we are sure they will be delighted to help and will know local dog trainers and / or pet behaviourists. Alternatively have a look at our UK dog trainers page or dog training books.
