my poor itchy babies - Page 2

Fleas can also be easy to miss. However, Blitzen, the OP says the vet did a skin scraping which would have picked up mange mites.
The Ivomec will work on fleas as well, so it might be worth a try. One of my dogs is extremely sensitive to fleas, and will itch like crazy with just a bite or two.

MAKE SURE YOU THOROUGHLY LAUNDER ALL BEDDING. Vacuum the places where the dogs like to lie. Vacuum all furniture thoroughly, including the cracks and crevices under the cushions.

I agree that it's unlikely to be food. I'm leaning Blitzen's direction. The likelihood of TWO dogs suddenly becoming allergic is slim. I'd look to enviroment...like sarcoptic mange or fleas.

Scabies are NOT easy to find in a skin scraping. It often takes 3, 4 tries to find them and there is a certain technique the vet needs to do to bring the scabies to the surface of the skin. It just can't be a scraping. Read the article I posted. Never overlook the obvious, always treat for scabies when the ear margins, elbows, stomach are involved, there is hair loss in those areas, there are "tunnels" visible under the damaged skin,  the scratching is intense 24/7 and other dogs and humans in the household are also scratching. Don't depend on positive skin scrapings. It's a no brainer for competent vets.

The result is that the mites can be difficult to confirm by skin scraping tests. (Probably mites are confirmed in 50% or fewer of sarcoptic mange cases.)

 

A few fleas are hard to see, but if you groom a dog with fleas standing on a sheet or towel and then use a tape roller to collect the hair and debris that has been removed you can see the flea feces - they look like pepper. Run some water over the debris and, if it's flea feces, the water will cause the black specks to turn blood red. Another no brainer.

these dogs r our kids. so work with me and understand if i become like a first time mother with a sick child............Sarcoptic mange mites are usually spread by direct contact from host to host., they have no contact with other animals of any kind, so where would it have originated from. and is "Heartguard (ivermectin/pyrantel)" that they take monthly a good treatment if so, since they are on that does it mean that i can rule out those mites?

they love to chew on, sometimes eat stick and pine cones, could that b creating an allergic reaction.......... could this just be cold weather, doc says that a food change takes up to 8 weeks to show signs that its working

Heart guard is not strong enough to kill mites.

Stay on one diet, stop switching.
Ivermectin is dangerous and i would not be administering it in a syringe from a bottle, there are safer ways, safer products.
Imported dogs could be alergic to a lot of things in this country same as you or me in a foreign place.
Mine itch more right now because it is winter and their skin gets dry, eggs raw, canned salmon, might help.
Avoid shampoos and products making miracle claims, dogs do scratch naturally.
My vet added and anethstetic to some ear drops once that helped imediately, but the itching comes back if it is alergies.
One treatment caused temporary loss of hearing in one of my dogs, temporary but lasted for over a year.
ear cleaning will not fix the problem and may add to the itching.
I put a dog down once who suffered badly and could not be cured, it was a monthly thing expensive and the dog would have spent his whole life this way, bad genetics.
try another vet is never a bad idea either.

 

is it worth it to take them to dermatologist
