If the problem is psychological there are many things in your pet's life that you can change to help with their itching. By changing their routine, you can help alleviate boredom. Many dogs get bored with doing the same thing every day or going for the same walk every day.
Change up their daily routine. Take a different path around the neighborhood or take them for a walk before dinner instead of after. These little changes in their daily routine will help decrease their boredom and stop them from itching.
By giving them plenty of exercises you will help them get rid of all the excessive energy. This will also make them want to take more naps, so they are not getting bored. Giving them toys or puzzles to play with while you are gone will also help stimulate their brains and decrease boredom.
If your dog suffers from anxiety while you are gone there are supplements that can help. CBD products are great to give dogs who suffer from anxiety. These will help keep your dog calm and stress-free. By offering your dog CBD products every day you can help keep your dog's anxiety away.
