Breed Mixed breed Cocker Spaniel
Right Combination!
My mixed breed spaniel has had severe skin infections for over a year caused by an unknown alergy. The skin on various parts of his body had crusty, yellowish growths that caused him to be miserable and his constant scratching and rolling around the carpet would only irritate his skin more so that those infected areas would become moist from a yeast infection...often compounded with bacterial infection caused by irritation from constant scratching his skin raw. He smelled horrible, poor ol' dog. The vet put him on Ketoconazole to kill the yeast, and Apoquel to deaden the itching. It worked somewhat, but it would always return. We bathed him weekly with PhytoVet CK shampoo that also contains Ketoconazole...and that helped. But all that...and it still would come back, and he'd go back to scratching again. So my vet thought perhaps an increase in the dosage according to his weight might help, and IT DID! My dog weighs 33lbs, and at supper only I give him 1/2 of a 200mg KetoConazole tablet and 1/2 of a 16mg Apoquel tablet...each completely wrapped up inside of a piece of American cheese and mixed in with his food. This has competely taken away his skin problem, and his coat is beautiful....no more scratching and no more hortibly stinky, miserable dog. And no more weekly baths. When I get him groomed... once a month...I now take the PhytoVet CK shampoo for the groomer to use instead of the one he normally would use. I hope that this can help someone.

Sick beagle
Has been on medication 2 days and is nauseous, and upset tummy. Vomiting today. I believe dosage is to high . She is 40 lbs. and getting a total of 800mg per day! I stopped it today . I will let it get out of her system and cut her back to 400mg per day. She is also on cream all for her toe nails.Veternarian looked up medication available before he wrote prescriptions. But after research I feel she is being overdosed ! Beware! Make sure you ask questions

Breed Old English sheep dog
Fantastic medication
Helped my Old English Sheep rescue that had horrible allergies. I took him to the Dermatologist specialist because after so many visits with my vet nothing worked so the specialist helped and she was able to get him on the right track and this was one of the medication. Well worth it. I do recommend

Definitely helped with cushings
When my Charlie was diagnosed with Cushings disease I was worried because he'd lost weight and hair in patches here and there. After taking ketoconazole he's back to his normal weight and his hair is coming back and the dandruff is gone. He seems like he feels better too!

Breed Mixed Shepherd
Wonderful!
My 60 lb shepherd mix was on 100 mg of Atopica daily and would still get occasional ear infections. Vet changed to Ketoconazole (3/4 tablet) and 50 mg Atopica and it made a huge difference. I am now giving this dosage every other day and will try to go to every three days. The Ketoconazole has been a life saver.
