Hi, thanks for using PetCoach! It definitely could be related to the food change or it is environmental allergies. The fall can cause allergies for sure. If you want to rule one thing at a time out, you can either do a course of antihistamines until the first frost and see if things with the eyes and skin improve as long as they aren’t miserable and itchy or change the diet first and wait to start the medication. Good luck! https://www.petcoach.co/canigive/dog/zyrtec/

Hello! All great questions and comments - and you're right, there's a lot of conflicting information out there regarding food. Some of the information you're going to find is based on personal preference or a value bias. Corn is a good source of digestible carbs, fatty acids, and protein - but these things are better digested in dogs than in cats (who are obligate carnivores), and some people prefer to minimize grains, so those people might state corn is "bad".... in my opinion, the focus on grains is based more on trends in human nutrition than evidence-based pet nutrition. Statements regarding what pet foods are "good" vs "bad" will also come from personal preference...your vet can probably explain what made them state that Purina is better than Merrick, and another vet might have their own input on the matter. I do personally like both Purina and Hills because I find their products consistent, reliable, and I like that those companies put a lot of their profits back into nutrition research to work on creating good foods - but that doesn't mean they're the only good foods out there. Raw food is another hot topic. I have worked extensively with dog mushers, and raw meat is a very common component to their food - and I'm fine with that. However, I also have a degree in Public Health, and know that raw foods increase the likelihood of foodborne illness such as salmonella both in the pets themselves, and in the humans who are in contact with them. So, again, there are going to be different sides to the conversation. It's confusing when there's conflicting information! Try to sort through what's based on research and evidence, and what is based on the personal opinions and biases of the speaker. Good luck! Hope this helps.

Before changing food I would actually recommend going to the veterinary visit you have scheduled. I would recommend getting some blood work done to make sure there is nothing systemically causing the weight loss. Once we determine there is nothing else going on with him then I would discuss what type of food he is currently on and seeing if a change in diet is ideal. Thank you for using Petco Pet Education Center, formerly Petcoach.

Thanks for using Petco Pet Education Center, formerly Petcoach! All the good allergy foods have a comparable price. The best in my opinion is the Royal canin Ultamino. This is the one recommended by the dermatologists at my hospital. Good luck and have a great day!

Thanks for using Petco Pet Education Center, formerly Petcoach! If she has not improved after doing an appropriate food allergy trial, then other possibilities in terms of allergies should be considered which include environmental allergies and flea allergies. This is possibly due to allergies. It really comes down to figuring out what is causing her allergies so that they can be treated or the specific allergen avoided. A secondary infection is likely and also needs to be addressed. There are many things that can cause allergies though in most cases they can be broken down into 3 big categories: flea, food and environmental allergies. Allergies are usually worked up in a stepwise fashion starting with flea allergies as this is the easiest and cheapest to take care of. If not on a flea preventative, then it would be a good idea to get started on one. If already on one then it would be a good idea to change to something else (there are many new products out in the market). If not improved in 1-3 months then it is time to move on and check for environmental allergies, as you have already checked for food allergies, which require blood and/or skin tests. Allergies can be very frustrating to deal with at first but so rewarding at the end when we are able to treat them effectively!
