I have a chihuahua about 10 now. She has been having seizures since about 5 years of age. I changed her diet to homemade chicken and rice. I boiled frozen chicken and added rice. She ate that for several years before the first seizure. The seizures are only about 1 minute. When I started baking the chicken instead of boiling it her seizures went from once every 6 months to every 2 months. I thought it was salt. I stopped the chicken and she made it 1 year without a seizure. This year she was diagnosed with a heart murmur and she got her teeth cleaned. She wasn’t eating well at all so I took chicken treats and cut them up very tiny and she went back to eating well. After 3 months of 2 chicken treats before every meal twice a day to get her motivated to eat can dog food she just had her first seizure again. Only 1 minute again. I checked the salt and it is lower than frozen chicken and FDA approved. This has made me wonder if she is just getting too much protein. She is off the treats now and eating well again so I hope we can stop her seizures again. I honestly thought I was the only person that this was happening to their dog. Hope this works. Good luck to you all. I thought this may help. I do believe it’s a sensitivity to salt or protein. I hope this didn’t cause her heart murmur. I feel it could have. 😢I don't have a dog with seizure but I'm wondering what dog food do you feed?
