I didn't care much about salmon oil and similar items, my dog was in a great state to begin with, but I received a sample of Best4Pets Wild Salmon Oil when visiting a pet expo and I took it home. I admit, I forgot it on a shelter and I doubt I would have remembered about it too soon... but Sasha decided to test it by himself. He took the small bottle from the shelter, tore it open and drank 100 ml of oil without leaving any of it on the floor. When I came home, the odor was hard to miss but the dog was really happy so I thought why not... let's buy him a big bottle and see how he likes it. Well, he does. He welcomes every meal with a lot of joy, he eats his entire portion without much fuss and he seems to be in great shape. His fur shines, his disposition is great, he is sharper and more focused than ever. Plus, I learnt to keep the bottle on the upper shelf because we have a constant supply of it.
