Tramadol is a terrible tasting pill. If you can't hide it in something she likes, I would have your vet call in a prescription to a compounding pharmacy. They can make any size dose into either a flavored liquid or a chewable flavored tablet. Mine like it liver flavored. If you don't have a local compounding pharmacy your vet can contact Diamondback Drugs in Scottsdale, Arizona.
Diamondback Drugs - Veterinary Pharmacy and Pet Medications
They are a large compounding pharmacy for animal medications and ship worldwide. Their prices are reasonable, their shipping is also quick and reasonable. They can compound just about any medication into appropriate doses and flavors dogs like. If Tramadol is a medication your dog takes regularly, it is definitely worth it.
