Licking legs

Question
QUESTION: My 4 year old male English bulldog has a very annoying habit. He leaks his upper part of his hands desperately without any apparently reason (no skin problems)besides that anytime he has a chance he eats the grass of the backyard. Any idea why is this happening and how I can stop it?
Thanks.
ANSWER: I think you mean "licking his legs". This is usually related to food allergies as well as the grass eating. They eat grass because their stomach is upset.

Try a change of food but do it gradually, perhaps over the span of a week by adding a little of the new food initially to what you're feeding now. Then increase the new food and decrease the old food daily until he's changed over.

I would try a good quality, natural diet like Innova or Wellness. You should see an improvement but it will take about a month.

QUESTION: Thanks for answering so quick. It is very supportive and sorry for the typo.In the past,we had the allergies problem with the food (he used to eat Eukanuba Fish and Potatoes). He used to have very bad diarrhea and we tried all kinds of food and we stopped all treats (biscuits, etc). Now he is eating IVD Rabbit and Potatoes and the change (took a while) improved a lot his excrement and also his ears itching. That's why I'm so afraid in making any changes to his diet again. However, I would love to know your opinion about the food he is eating now. Which will be the difference among the ones you are suggesting and the other?. Thanks a lot.

Answer
I'm not familiar with the food you're using but you should keep the dog on a lower protein, lower fat diet, even a low calorie diet is ok.  Protein should be around 24 % or even a little less. High protein and high fat can contribute to intestinal problems in a dog that isn't very active. It's too rich for them.  If what you're feeding is a canned food rather than kibble, I would switch to dry kibble and stay there.

Also beware of anything with peanut oil or peanut flavoring in treats.

Perhaps you might be able to find an animal nutritionist in your area who could help you with this.
