I own a female Jack Russell/Chihuahua who is four y/o (I adopted her at 7weeks old) & she is my heart. She is an active dog who loves lots attention. I also occasionally take care of a 10 y/o Pomeranian male who is the happiest lil fellow. I have experience administering oral medications to dogs, even to the type who really dislikes taking them! I spend a lot of time and attention on the furbabies. I think of them as angels, all of them.
