I just worry about him because he does the hack like the dog in the video since he was 4 months old so I know he has trachea problems. he will do that noise at least once a day. I did show the vet his tongue and she felt it did not look blue to her. She said as long as his gums look okay and they where pink. Thanks for every ones help.
