Hi everybody, simba our 3.5 month old puppy did something really weird yesterday, and then again today. Yesterday a friend took a picture of him with flash and he starting doing this extremely fast and loud panting. then he curled up and looked like he was going to throw up. Then today he went up to meet someone jumped all over them and after 30 seconds of that she got up and walked away. As she was walking away he did it again, very fast panting approximately 15is breaths it was really scary. Does anyone know what's going on?
Thanks in advance,
Suki
