The family I live with owns a 14 year old shitzu dog. She's adorable, but she's been having these....seizure-things. She gets all twisted up and cries; it's happened twice. The lady of the house has looked up whether cooked eggs are bad (every once in awhile she gives her one) and according to people online, once in awhile is fine. The dog is old, but are COOKED eggs bad for her? Please, if you offer your opinion, offer sources too. Thanks.
