Limited ingredient diets come with one major benefit - pet parents are able to identify exactly what goes into their dog's body and avoid any specific ingredients. While a suitable diet for many dogs, LID diets can also be great for dogs with food sensitivities.

And thank you for your question! Hills Z/D is a great allergy diet. The way it works is that it is a hydrolyzed protein diet meaning that the proteins that normally cause allergies are too small to trigger the allergy with the hydrolyzed formula. Hill's Derm defense is a great food as well. The way that Derm defense works is that it strengthens the Skin Barrier and it has multiple antioxidants and phytonutrients period before switching to Derm defense I would suggest speaking with your veterinarian who previously placed Louie on Z/D to see if this would be a good switch. Some other things that help with allergies would include omega-3 fish oil supplements and essential 6 Spot On by dermoscent. Help this guide you in the right direction. Please do not hesitate to contact me with any further questions or concerns you may have

Science Diet is an excellent food but as you have noticed their over the counter foods typically don't have fish. They do have a prescription diet with fish but it can be expensive. I included a couple links to a couple different types of food that contain Salmon. https://www.chewy.com/purina-pro-plan-focus-adult-sensitive/dp/128666 https://www.chewy.com/purina-one-smartblend-sensitive/dp/37688 Thank you for using PetCoach.

I have had good success with the derma 369. If she has a lot of skin problems then I would talk to your vet about writing a prescription for derma strength pro. This one is a little stronger but is a prescription. I hope this helps!

I like hydrolyzed protein diets for the hypoallergenic diet trial. Hills z/d and Purina HA are my 2 favorites. They make the protein sources so small that the immune system can not recognize it as an allergen. Diet trials should be continued for 12 weeks to know if they are helping. Best of luck and thank you for using Pet Coach.

Hello, and thank you for your question. Dogs with IBD should definitely be on a hypoallergenic diet of some sort. The good news is that there are a wide variety of hypoallergenic diet options. Hill's i/d is actually NOT a hypoallergenic diet. It is a bland diet designed for sensitive stomachs, but not for food allergies. There are two main categories of hypoallergenic diets: 1) Novel protein diets, which consist of protein sources that most dogs have never been exposed to before. This includes venison, duck, kangaroo, rabbit, etc. You would choose the novel protein that you are sure Toby has never eaten before, including through treats or table scraps. 2) Hydrolyzed protein diets most often consist of hydrolyzed soy protein, where the molecule is broken down in such a way that the body does not recognize it as an allergen. These are a good option as well, but it is not guaranteed to work in all dogs. Both types of diets come in wet and dry options (e.g. Hill's z/d comes in wet and dry). I would talk to your vet about trying a brand with a wet option. Once he is weaned onto the new diet, he should be kept on it for a minimum of 8 weeks with no other treats or table scraps. I hope this helps, and that Toby gets better soon!
