I have 3 dogs. 2 beagles and a jack russell.They are my babies. Last year at this time ,I had this problem with just the 2 beagles. They are chewing and scratching alot. Driving me in sane. Went to the vets. gave them advantage and pretazone.sp.I am not to sure which one worked. but it did.....Didnt think any more about. Till this year.Again going threw the same thing again. I looked up when last year then went. It was the exact time frame as of last year. SO i was thinking maybe it was alllergies ....So the vets again. Put both on pretazone.sp. Worked for 3 days ....Thats it. I didnt give them the advantage because that do have flees. ect. How can i stop this. The think is they mostly chew on the feet and up the legs. They dont chew their be hinds. But they are chewing enought that they are bleeding from it. I keep checking. My jack russell dosnt have this problem and she sleeps with them and likes to clean their faces. lol. The same food. They are on no grain dog food. orijen. No bathing...did that last year. Just dried out more. I dont know what to think. As i recalled last year ,when the first frost hit. THey stop itiching. I feal sorry for them. WHen you touch there side. Their legs start going...Which is normal from nerves,but more senitive now ...
