My name is Egypt!

She’s 3.5 years old. We rescued her from an awful situation - she’d been chained up her entire life (over 3 years at the time), outside with no shelter. She’s a total sweetheart, and incredibly smart. Loves people, zero aggression towards them. She’s great with the other dogs she’s met too (but has limited experience meeting dogs), other than our first dog. Our first dog hates her for some reason, and they’ve never gotten along. In the past few days, things have escalated to large fights between the two of them, with no triggers or warnings to speak of. Never any fights with the other dogs we have or any aggression towards people. With this being the case, with my wife pregnant and due soon, I just need to rehome this one to avoid any further stress for my wife.
