Hi do all anthistamines work the same ? Looking them up online they seem to have different ingredients different bases My dog takes piriton twice daily but hand on heart I'm unsure if it's doing anything so would another brand be different or not ?

In general, antihistamines are not very effective in dogs for itching - so unfortunately, it doesn't surprise me that you aren't seeing much effect with Piriton. You could certainly talk to Lily's veterinarian about trying a different antihistamine such as hydroxizine or diphenhydramine, as some dogs may respond a bit better to a different drug.
