most important thing is to switch Abby food.

Sounds like food allergies

Eagle Pack Holistic
California Natural
Wellness
Canidae
Natural Balance
Timber Wolf
Pinnacle

are some choices, you may want to stick with
a Lamb base food or Duck, Buffalo.

commercial foods, stuff you buy at a grocery store or discount chain store tend to be 90% grains with no real meat and this is where our pets get allergies, bacterial infections and major health problems.

oh and this goes for treats also, best to try carrots or apples or liver treats rather than ones that have alot of grains. Just stick to the brands above for treats and you should be ok.

Dick Van Patten, Natural Balance makes these meat rolls you cut up like a sausage, those are great for treats. Freeze dried liver treats are good to for allergy dogs.

e-mail me if you'd like more help

supplement isn't always nessarry if you feeding a quality food but added Flax Seed Oil to the food a few times a week can help without any side effects.
