You have received great advice, all I can do is echo it!

Pumpkin - canned, and NOT pumpkin pie filling which includes spices etc. - about 2 tablespoons in the food daily will help w/ anal gland issues. As mentioned, you need to bulk up the stool.

Grain free diet - your pup will be healthier all around, better able to fight off infections when she does get them. Any rated "6 stars" on here are great:

What laundry detergent do you use? Many dogs are allergic to Tide. Use a "FREE" laundry detergent with no dyes, etc. as this may also help (and can't hurt!)

For the itch: use Gold Bond Medicated Powder. Not this is NOT a cure of the underlying issue, which you should continue to work on. This gives the doggie some relief from all that ITCH!

You said urinary infections, plural. In a dog of 9 months, this is worrisome. Consider using a supplement. Dr. Foster & Smith have Cranhealth which is advised for dogs who have had bladder stones. One of the common types of bladder stones starts with chronic UTIs, and the dog may have stones by age 4. This is a prevention measure:

Any dog with "drop" ears, like your Cocker and my bichons, need to have the ears kept clean. You can get an oti cleanser and use that once or twice a week to prevent the infections. This is the one I use (this is NOT the site I order from!)
