Giardia treatment Advice

Hello:)

My 4 month white Swiss shepherd (genetically basically GSD) has Giardia.

We got Panacur but she realllyyy doesn’t take it well.

At day 1 of treatment we also switched to raw food diet.

Her diarrhea instantly stopped so I called the vet if I can stop Panacur now too, because he told me he only treats dogs with symptoms.

But… Claude and ChatGPT say I should be careful especially because she’s a GSD which have low immune system (igA?) anyway

So I would love to hear some expert advice or suggestions.

Can I safely stop Panacur treatment now and focus on building her immune system?
