Thank you readers for your concern, well wishes and kind advice after Saturday's incident.
I took Bertie to the emergency vet this (Sunday) morning, and she noted the wound in his side was quite a deep one and suggested I leave him to be sedated and they would clean it up thoroughly and check him over.
Imagine my horror when later in the day the vet phoned back to tell me Bertie's injuries were rather worse than she'd initially thought. It seems Jake's teeth must have dug deep and dragged some of Bertie's skin and flesh inside, creating conditions for an infection, and a large cavity full of puss had already developed beneath his shoulder, which required a big incision to clear out. The vet also noted other signs of trauma on his neck.
The poor wee lad.
I finally went back to the vet's to pick him up this evening.
What a sorry sight.
We returned home armed with antibiotics and pain killers. Tomorrow I shall stay at home to keep an eye on him and make sure the wound drain does not clog up. We go back to the vet on Tuesday.
My arm, by the way is fine, just a bit sore and bruised but nothing compared to what Bertie is going through.
One way and another, it has been quite a week here in Aberdeen!
