Our old dog Dixie is suffering from some skin allergy that makes her scratch and lick constantly.  The vet says that all dogs around here are suffering too.  The shot had little effect, the oral meds have some effect, and adding benadryl does no good.  She just sits there licking costantly with the schorping sound and it’s driving me crazy.  I hope we have a hard freeze soon to kill whatever plant is doing this.
