It's so hard to watch Tucker go through this, and it's really thoughtful of you to be paying such close attention to how he's doing. The short answer is: yes, dogs absolutely can grieve, and what you're describing is a very recognized pattern.

Dogs form genuine social bonds, and when a companion animal dies, many dogs show behavioral changes that look a lot like grief. Reduced appetite or becoming picky about food is one of the most commonly reported signs. Others include:

  • Searching the house or yard for the missing companion
  • Being quieter or less playful than usual
  • Sleeping more, or sleeping in different spots
  • Seeking more attention from you — or, in some dogs, withdrawing

These responses are real and they matter. Tucker isn't being difficult — he's adjusting to a significant change in his world.

Some things that may help during this time:

  • Keep his routine as consistent as possible. Regular walk times, feeding times, and play sessions give him a sense of predictability when things feel uncertain.
  • Offer gentle engagement. Short play sessions, a new chew toy, or a sniff-focused walk (letting him lead with his nose) can provide mental stimulation without overwhelming him.
  • Sit with him. Your calm presence is genuinely comforting. You don't have to "do" anything — just being nearby helps.
  • Try warming his food slightly or adding a small amount of low-sodium broth to make meals more appealing, if he's eating less than usual.
  • Avoid reinforcing food refusal by constantly switching foods — a little patience and consistency at mealtimes usually helps more than variety.

Most dogs begin to show improvement within a few weeks, though some take longer, especially if the bond was very close. Three weeks in, it's reasonable to still be in the thick of it.


When to see your vet: Grief-related appetite changes are common, but it's important to rule out any physical cause for the pickiness — especially since Tucker's age is unknown and some health conditions can look just like grief. Please schedule a vet visit within the next week or so if:

  • He's eating significantly less than half his normal amount
  • He has lost noticeable weight
  • You're seeing vomiting, diarrhea, or lethargy alongside the appetite change
  • He's drinking much more or much less water than usual
  • Things aren't improving at all after another week or two

A vet can also talk with you about additional support options if Tucker's grief seems prolonged or severe. You're doing the right thing by paying attention — Tucker is lucky to have someone looking out for him.
