Trazodone, with or without gabapentin, reduced stress-related behaviors in shelter dogs
Delabar et al. randomized shelter dogs to four groups before surgical neuter: trazodone (8 mg/kg), gabapentin (25 mg/kg), both drugs, or neither. Each dog got a dose the evening before and the morning of surgery. Blinded observers scored 15 stress-related behaviors (13 made the final analysis) from short videos taken with and without a person present.
“the trazodone and combination groups had a significant reduction in mean behavior score … and the gabapentin group had an increase in mean behavior score.”
60 dogs across 4 groups works out to roughly 15 per group. The abstract reports no effect sizes. Each observation was a 1-minute clip, and the setting is the pre-surgery window only. Enrollment ended in 2021, five years before publication. No funding or conflict-of-interest statement is visible in the record.
If your vet team already gives trazodone before surgery, this supports it for visible stress around the procedure. It doesn't show that gabapentin alone helps, and it says nothing about stress over a long kennel stay.

A proposed shared vocabulary for fear vs. frustration
Wilson, Soulsbury, and Mills (University of Lincoln) review the clinical animal-behavior literature and propose functional definitions of fear and frustration, using dogs as the model species.
“Our proposed definitions for fear and frustration structure and unite existing theories”
This is a conceptual paper and hasn't been tested. The abstract doesn't describe a systematic search. It isn't specific to shelters. The authors declare no competing interests.
Useful when your team is arguing over whether a barrier-reactive dog is scared or frustrated. It gives you shared language, not evidence about which intervention works.

Older dogs had much lower odds of adoption in Italian shelters
Corsi et al. analyzed national-database records for dogs admitted to 18 shelters in Abruzzo during 2023–24.
“lower odds of adoption for animals aged 1-2 years (OR = 0.53) and over 2 years (OR = 0.31)”
The regional adoption rate rose from 45% to 49.6%, and average length of stay fell from 104 to 94 days.
This is descriptive registry data from Italian shelters (8 private, 10 public), so applying it to US open-admission shelters is a stretch. The abstract doesn't name the age group the odds ratios are compared against. It includes no behavior data, and no funding statement is visible.
It's another data point for putting your marketing and enrichment effort behind adult dogs. How well it applies to US shelters is unknown.

In senior dogs, touch sensitivity and unprompted vocalizing were linked to poorer quality of life
Kottferová et al. surveyed owners of older dogs online. Increased response to touch and vocalizing with no apparent trigger were each independently associated with poorer quality of life as owners perceived it. The number of health conditions was not. Better mobility was associated with lower odds of poorer quality of life.
“Multivariable ordinal regression analyses showed that increased response to tactile stimulation …”
The data are cross-sectional and owner-reported, and the respondents selected themselves online. The links are associations, not causes, and the authors say so. They declare no competing interests.
With senior surrenders, new touch sensitivity or vocalizing out of nowhere is a reasonable cue to ask for a pain workup before treating it as a behavior problem. Treat this as a hypothesis, not a protocol.
