I need some advice. We rescued a dog only 1 month ago. She is a lovely crossbreed of unknown pedigree(was a stray) Anyway she has been really good so far, settling in more and more each day with very few issues. But, my eldest DS seems to be allergic. He has never shown any symptoms around dogs before. He used to get a rash around cats but don't spend time near cats anymore. I can't bear the thought of my child having to take antihistamine every day but feel awful about the dog especially as it was my other DCs dream to get one. So, does anyone know if dog allergies(if it is that but seems to be) calm down or clear up completely? Help!
