I come to you guys with another problem that I have noticed with Shelby. I just noticed this last night and then agian a few minutes ago. She was laying on the floor here with me and she will start basically gasping for air. It seems like she is having problems breathing and will suck in air really hard and then let it out fast. I don't know really how to explain it but it's almost like she can't really breathe. It will only go on for a few minutes and then right away it will stop and go back to normal. Does anyone know what could be causing this? The other night I did notice a small lump on her upper neck too. I don't know if that is important but I thought that it would be best to mention that. The vet doesn't notice anything wrong with her but I just noticed this gasping last night so I have never brought it up.
