Need some advice

I have a friend whose dog passed away two weeks ago. She had gotten a divorce a couple years ago and that dog was her world. When it first happened I texted her a couple days in a row just to.make sure she was ok. She has basically shut herself off from the world. Posted a photo of the dog as her profile photo on her facebook page but did not announce the passing. The third time I texted, I basically said I dont want to be a pest so just know I care, my heart goes out to you and if you need to talk Im a phone call away. She responded saying thanks Chuck I appreciate that. Its been almost two weeks now. Should I call to see how she is? Should I text? I dont know what to do.
