Hello,I would love to help I just have a few additional questions. After your reply please allow a few minutes for me to type your answer.
How long has this been going on?
Any chance he got into something toxic?
Is he responsive?
Any head tilt or rapid eye movement?
What color are his gums?
Sorry I need some additional information so I can try to narrow down the possibilities
Can you explain how he is walking?
Is his stomach harder or larger then normal?
Ok thank .
He needs to be seen by a vet immediately.
My first two thoughts with these symptoms is either a bleed in the spleen or problems with the heart.
The pale gums hard stomach and difficulty walking often indicate a mass on the spleen that is beginning to bleed.
This breed is very prone to problems with the heart and the heavy breathing and hard stomach could be due to fluid building in the abdomen.
I really try not to send owners to the emergency unless absolutely necessary and at this point I think your boy may be in real trouble.
If you need help locating an emergency hospital in your area please provide your zip code.
Please let me know how he is doing I am very worried about him.
