We relocated to Malta in late October of 2015 so the start of summer is a new experience for us and our dog. I have recently started walking him on the rocks by St. Julians which he loves and has now become intimately familiar with the area. In the last week I have noticed he has a red rash on his muzzle and eyes, and he is now scratching a lot. He has now been treated with the new frontline product that kills sand fleas I am told. I am a bit concerned that the redness around his eyes and muzzle is due to the salt on the rocks. Is this a common thing for this type of environment. What are things that I should look out for in Malta during summer that may adversely affect my dog. He is a 2 year old chihuahua.
