I am new here and my wife and I have 2 bassetts. My female is named Alli and she's 1.5 years old. Sometimes when she lays down, she seems to hyperventilate. It is worse after she's been active and only lasts about a minute. That minute seems like forever when she can't catch her breath. Is this a common ailment with bassetts? Buddy is my male and he is about 8 months and has not shown any signs of having the same problem. They were both sired by the same dog. The veterinarian hasn't ever seen her do it and says all her tests come back normal. Looks like asthma or allergies or something. Any info or suggestions would be appreciated.
