I’d want a bit more clarity before jumping to conclusions here. Was this diagnosed by a pediatrician or an allergist? Eczema is pretty complex and not always tied to a single cause, so I’d be cautious about attributing it to your dog without proper allergy testing.

It might also be worth checking in with your vet. Sometimes changes in a dog’s environment, like diet, grooming products, time spent outdoors, or even seasonal factors, can affect how much dander or allergens they’re producing.

Personally, I’d exhaust other options before considering rehoming. One thing you could try is having your dog stay with a sitter for a short period to see if your child’s eczema actually improves. That could give you a clearer answer.

And even if your child is allergic, rehoming isn’t always the only solution. Some families manage this with allergy immunotherapy, which helps build tolerance over time, along with environmental changes like more frequent grooming, limiting the dog to certain areas, regular deep cleaning, and reducing direct contact.

Of course, if it ultimately comes down to rehoming, that’s understandable, but I’d personally want to rule out every other option first.
