Hello!  I'm sorry to hear that you and your dog are having a bad time following chemo.  I'm not clear whether this is a side-effect of chemo or a new symptom, or even what chemo meds / dose you are using.   However, if you suspect that a dog is in discomfort or distress then it is not really something that will wait until Sunday; please call your veterinary team and report the signs.

Possibilities may include a drug reaction, eg a skin reaction to the chemo, or an unrelated fever, anxiety or completely separate disease process.  However, phone triage by the vets who know her case is the best place to start.

If they are not available out of hours,then it is possible that the out of hours team will be able to access a copy of her notes.
