All those remedies used to work but this new strain of kennel couch is hard to get rid of seems to just have to run its course . I need new suggestions if any body has some.
I have always had luck with Teramicine. I'm sure the spelling is not right but I get it here at the feed store. It's an antibiotic that comes in a powder package, I put half the package into 2 to 3 gallons of water. Let them have that as their drinking water and change it out ever couple days usually the cough is gone in a few days.
tylan works good as well as treating their drinking water with sulmet, you can get it at southern states or online, it is for respiratory problems in chickens but will kill the bacteria that causes the cough and will keep it from spreading thru the kennel. just a couple capfuls in 5 gallons of water, make sure you keep water there as it has sodium in it and will make them drink, sulmet also good for prevention of coccidia in pups and dogs, wayne
