I realize I'm digging up a REALLY old post but thought I would use it as a starting place, please advise if there is a more recent one to use instead.
My beagle has the same issues, very red itchy belly and butt. Her beagle feet seem to irritate her some, chews on them some, but not red or much of an issue. She seems to enjoy rolling around on me when she's particularly itchy, scratching her eyes and nose.
Changed food multiple times, can't remember how many much less brands. Ensuring each had good ingredients different than the last to eliminate possibilities hopefully, to no avail. She's seen her beagle Dr. many times and typically has around 4 steroid shots a year that help after a couple days of clearing up then she's pretty good for between 2-4 weeks or so. Baths with good oatmeal shampoo every 3-4 weeks, changed shampoos as well, again ensuring quality and change in ingredients from last with no significant difference. Stuck with the oatmeal shampoo that seems to provide some temporary relief, like maybe 5-10% for a few days nothing significant.
Changed our laundry soap, household cleaning items etc. No fleas, takes good flea/heartworm meds, can't recall name off hand, beagle dr knows what I need so I just pay and go... can look next dose I pick up but it's happened on others and without and basically quarantined for a week or so to see...
It's been a while so don't recall numbers but testing was more than we could afford then and times are tighter now unfortunately. It's possible the tests aren't so bad now but I'm not holding my breath on that possibility really but will check. Anyone have any rough ideas, I'm sure it can vary quite a bit but maybe a few have recent experience that will provide an idea?
I've not done the raw diet but might give that a try if possible after researching how to do it and if possible right now.
She's healthy otherwise, nice coat, soft and shiny and as thick as ever! She acts fine, bounces around and plays then lazy beagle etc.
She's gotten a few infections on her belly from this, she scratches on the carpet, it's looked a little R rated the way she does it to many an outsider...
Antibiotics cleared up the infection but rash/itch remained.
She's 11-12 now, I have some memory issues from accident so not great with certain things if you haven't noticed, sorry about the little missing pieces. I know that's close though. She's had this most of her life, I would say at least the past 6ish years.
Recently gave her a script from beagle dr, sorry don't know name, but was expensive and told it usually is great or worthless. Tried for 2 months and nothing.
Anal glad removed years ago without issue. Spayed while very young without issue...
Sorry so long, trying to cover anything I can think of that might help off the bat.
Any help is GREATLY appreciated! That beagle's my little buddy, she took care of me after my accident, wheelchair then learning to walk again over about 2 year span, and I'm going to take care of her for sure!
