Looks like our greyhound may be making his last visit to the vet's today.
He's quite old, frail and arthritic, but on Monday couldn't stand up or sit down (he did this once before; was cured with huge amounts of antibiotics). Vet prescribed painkillers and antibiotics which seemed to work until yesterday when he developed huge blisters on one leg and a stonking temperature. Vet said we'd probably have to get him put to sleep if he didn't recover.
The blisters have burst and he now has giant cuts (aided by his tongue) and is lying almost motionless in the sitting room. Even more motionless than usual, which for a greyhound is quite an achievement.
Children are pretty cut up about it. The youngest was reading to him; the second eldest who lives for him has gone very quiet.
EDIT: From a purely selfish point of view, we can't keep getting up in the middle of the night to change his dressings and clear up after him. Sounds awful, but there you go.
