PARVO F STRAIN, there seems to be a huge outbreak in the parvo virus department and it isn't your traditional parvo most of us are used to.,and traditional treatments are not working,my advice is to vaccinate early,I start at 5 weeks old or older if they will be with us for a while like the Tiny l.h. chihuahuas,I do them at 7 weeks.remember to be very careful when introducing your new puppy to the world they are not protected until atleast 2 weeks from the first shot and very well protected 2 weeks after the second shot.so if your in a rush to show off your new puppy,please take pictures and send them.be a good and safe owner and PROTECT YOUR PUPPY!!take your puppy to the Vet right away and go to only a top reputable Vet as not all of them are good and truely care about your animals welfare,I recommend the Tropicana Animal Hospital.Dr.Nave is a surgery specialist there but only hires the best to take care of your needs as well as your animals needs. .................................. http://www.parvobook.com/..................... http://www.edmontonsun.com/Comment/2007/07/26/4369079-sun.html................................ http://www.parvobuster.com/value-packs.php.............................. SARCOPTIC MANGE, this is a nasty bug and undetectable through skin scrapings,so your vet won't notice it if you take your puppy in with it.what to look for is scaly,moist sores that itch and spread and create hair loss.if you notice this.then don't wait to spend a ton of money at the Vet and get serious about it,use 10 units of injectable ivermectin under the skin every week for 6 weeks and buy peroxide and borax,mix 1 cup peroxide and 1/2 cup borax to 1 gallon of water and dip your puppy or dog in it every day after 1 week refresh the mix and continue through the six weeks or when you notice the scabs are healing and the skin appears to be getting back to normal.can be from 1 week to the full 6 week treatment time.you would need to use a insulin needle and syringe, that measures the best and more accurate,to avoid over dosing..feel free to contact me if you have any questions about this.
