first i would say calm down lol,its not the end of the world,mange is easily treated and most dogs get over it well as many have said, ear infections are easily treated also,if its a bad infection then the vet can give drops to clear the initial infection,when the infection has gone then try extra virgin olive oil with lavender mixed in it ,put a few drops in the ear ,let it sit for 30 mins then wipe out ,you can use this mix to try and clear the infection ,use it every couple of days till the infection has cleared,then use it once a month,i always use colloidal silver in my dogs ears after using the oil mix ,most illnesses are the result of a weak immune system and this too can be rectified with the best diet and excersize that you can give your dog,i give my dog emu oil as she doesnt tollerate fish very well but both are a good suppliment,i do not know much regarding kibble as i raw feed which boosts the immune system,just try and relax,very hard i know but the more stressed you get the more stressed your dog will become,its all fixable it just takes time and effort,my own dogs immune system is weak due to vaccination damage causing allergies so i have learnt to take it in my stride now and not to panic,karen
