I'm not saying that's what your pup has but keep an eye on her. My pup's symptoms were frequent urinating, usually in little piddles or drops, green discharge (the source of the metallic smell), and not being able to hold her pee for more than 2 hours at a time during the day (even in the crate).
If you suspect a UTI, get her to the vet asap to get it cleared up as soon as possible. Hopefully it's not but better safe than sorry!
Agreed, sounds like a UTI. You may be smelling iron. Iron is an essential element of the heme group within blood. Presence of bacteria which could be causing a UTI in your pup could be breaking down the heme group of blood (usually present as a result of a UTI due to damage by bacteria), causing an accumulation of iron in her urine. Additionally, as Ranger posted, when the heme group of blood is broken down by bacteria, it produces a green color, which would make sense why the green discharge was the source of the metallic smell. I would most definitely take your little girl straight to the vet and get her on some antibiotics. Best of luck, hope she's feeling better soon!
