He has developed the runs, wouldn't look at his food (not like greedy Charlie at all) and was trying to be sick. Seems it could be my fault (sorry Charlie) as I tried him on a different food last night (Natures Menu) could have been too rich?? Anyway vet said he thinks it is dietary. Poor Charlie had his temp taken (he growled at the vet!), an anti inflammatory jab, course of antibiotics, pack of RC sensitive and more ear drops. Glad to report his ear mites have gone and his infection is almost clear. I am £59 lighter too!
However he has been playing with his toys and seems ok in himself so am going to try not to worry but for me that is almost impossible. Think I am becoming neurotic.
