[Chihuahuas] little pig noises

[Randi Grennan]

  I adopted two dogs from the pound the vet said she is 3 1/2 pounds no worms 
everything great but urine infection probably two years old. They said a guy 
brought them in and said he went to clean a house cause the people left and 
they left these two behind.  So the pound kept them for ten days just in case 
the people came back for them.  The pound was cold in there too.  Her lungs are 
clear but she sounds congested sometimes.  He put her on liguid Clavamox for 
fourteen days. He said she might have gotten a very mild case of kennel cough.  
 It really sounds like little pig noises.  Just wondered if the toy ones just 
make sounds like this? Thanks
