I posted here a few weeks ago about my beautiful Cavalier KC Spaniel who sadly passed away. She had several tumours and had to be PTS.
DH has just taken our other KC to the emergency vet. He was woken by our boy moaning and thrashing about. I didn't hear this so DH woke me.
Mr C (our boy) seemed to be struggling to breathe & his eyes were unfocussed. He has been to vets this week with suspected kennel cough and on anti-bs for an infection. Seemed to be perking up today but slow on his walk tonight. He has a moderate heart murmur but vet seemed to think this was ok.
Just didn't know what to do. Stroked his head & ears while DH desperately tried to call a 24 hr vet. If I stopped stroking him he moaned. I am so worried and so so sad. It's 2.30am and DH has just taken him. I am waiting for a terrible phone call.
It's heartbreaking. Mr C is only 6 yrs old. I adore him. 
Don;t know why I'm posting really other than to tell someone who understands. I love that dog and my heart is breaking.
