We've reached the end of the line, as far as chemo goes. The last time, Herbie was weak for a fortnight after the treatment, but the lumps only stayed down for a couple of days. I talked things through with the vet, and he felt that it's not a good sign that Herbie's not bouncing back from the chemo. There's a risk each time with the doxorubicin, and it's better that we leave him as he is now, happy and wanting walks, though with a lumpy neck, rather than making him downright miserable for little progress.
In theory, 80 per cent of dogs achieve remission with chemo - for the stats to work out, there has to be another 20 per cent, and unfortunately Herbie's in that group. So, all I can do now is feed him lumps of chicken, and enjoy the time we have left.
