My greyhound also has signs of LP and we saw a vet but she is reluctant to prescribe me doxepin to help her out. She says there are not enough studies out there to prove its efficacy. Yet, I went online and found these two articles which both show evidence by vets that it can be useful.

I printed these out and showed them to my vet but she won't change her mind. Wondering if others here have struggled as well and what I can do to convince her. I am almost tempted to purchase from online pharmacies but they look non reliable and afraid they would just take my money and not send the medication. Lately I saw a person on a forum who had a dog with LP who passed away and he was willing to ship them to me.
But is it so risky to give these pills a try? I hear it only may cause a bit of a sedative effect. Go figure why my vet is so stubborn! I feel like switching vet just for this, but she has been great over the years other than this really.
