I have two dogs a great dane and lab my great dane is 1 years old and a boy and chocolate lab is 4 months old and a girl they are lovable and very high energy so any age of dog don't bother me I can also help with potty training and basic commands since my dogs are trained and was trained at age 2 months. I can help train to sit, lay, down and stay. It does take time to train but it's amazing how much they will listen. I love and care for animals and take my time for each individual. I also make dog treats from scratch so they can always have something different but healthy. So let me know if any dog is allergic to anything.
