I spent 20 years in the home security industry. Trying to fortress and alarm your apartment is a losing battle in my experience. A decent door deadbolt and normally secured windows is as good as trying to make a fortress. Never lock a door KNOB. It is a waste of time and causes people to forget to lock the deadbolt.
A fortress makes your home look like a target. A dog has drawbacks. Biting neighbors or yapping at anything creates an additional stress. A very well trained dog would be great but it takes strict discipline to train a dog for a family security need.
We have had two home protection dogs killed by police lately here in Idaho.
You can buy "Barking Dog" alarms.

Added L-Tryptophan and successfully stopped all paroxetine after 3 months of tapering down. I currently take 500 mgs of L-Tryptophan when I wake up, 500 mgs after breakfast with my vitamin regimen and 500 mgs late in the evening.
As of Nov 15th, Due to high stress issues resulting in PTSD, my docs put me on three meds. Clonazepam (Klonopin, a dreaded benzo but only for 30 days ) 12.5 mgs twice daily (Doc prescribed 25 mgs twice daily but half a tablet is doing good) , citalopram (Celexa), an SSRI , and olanzapine (Zyprexa), an atypical anti-psychotic before bed. I have lost over 30 pounds since mid July. The olanzapine is supposed to help me gain some of it back but it has just stopped the weight loss. They took me off the gabapentin. Feeling much better.
