@nick4 I'm assuming your pup has had Fanconi testing or is clear by pedigree? It usually causes decreased appetite, so I wanted to make sure it's been ruled out.
Otherwise, I've always found basenjis who are 'only children' are really fussy eaters--no siblings to steal their food if they walk away. At 5.5 months, it might also be he's missing the his mom & littermates, since b's are social dogs. Does he spend a fair bit of time alone? That's often stressful for them, and stress affects their appetite a fair bit.
You could try a commercial raw diet, mine definitely prefer it to kibble. Earthborn Meadow Feast is another kibble that's tempted mine when they weren't hungry.
Also, make sure the kibble is stored in a cool, dry place out of the sun in the original bag. If you economize by buying large bags, store the bulk of it in the freezer, taking out about a week's worth at a time. It can go rancid quickly once exposed to air, especially in hot weather. I'm also cautious about buying kibble in the summer months--I think it might go rancid if transported in unrefridgerated railcars or trucks that stand in the sun for hours. I have one boy with a sensitive nose and even more sensitive gut--I pay attention when he refuses food, he's my canary in the coal mine.
If he doesn't eat, pick up his food and either discard or bag it & put it in the freezer. Leaving it down for him to eat later will make him a pickier eater. It's better for training & housebreaking if he eats (or not) on a schedule that YOU dictate. Good luck!
Antigone, I've heard many comments regarding rescues (or coordinators/fosters) who 'keep dogs for themselves' and would like to address that issue. I live across a provincial border from the 'puppy mill capitol of Canada,' and have become an unwilling expert in rehabbing & rehoming PM dogs. I don't think you--or anyone else--would make that comment if you'd actually cared for one of these dogs. Moreover, it's difficult to find appropriate forever homes for many of them, since they come with behavioural or health problems that adopters either aren't equipped or willing to deal with.
I've adopted two of my own fosters: one so incredibly timid that I've never been able to pick him up or put both arms around him unless he's tranquilized, otherwise he bites; Another I received as an 8 week old foster with cranio-facial trauma--he's visually impaired and is mostly incontinent, although he's improved somewhat over the years. I didn't 'want' to adopt either dog--I wanted to continue fostering--but the fact remains that they--and a number of PM dogs--were and are 'undesirable' to the average adopter, and often remain with the foster parent.
Also, even PM dogs less impacted by their experience awaken a protective instinct within their foster parents, who then--not surprisingly--become unwilling to give them up. I can vouch that it's very, very difficult to nurture a broken creature who comes to you encrusted with feces and mange, who stinks to high heaven despite repeated baths but still needs the warmth and security of curling against you at night--then 'betray' them by handing them over to a stranger.
The thing to keep in mind is that rescues are about keeping the dogs safe and happy, first and foremost. Often the best home for them is where they feel safe and loved, which is sometimes their foster home. Anyone who gets mad at THAT probably isn't the most ideal applicant. If someone really, really wants a rescue, maybe they should become a volunteer first, just to see what's really involved with caring for a rescue. Contrary to popular belief, young, unaffected rescue basenjis are few and far between.
What a cutee! Is this your first basenji? Always a shock the first time you turn around and are suddenly eye-to-eye with a puppy you're used to seeing on the ground! I had a foster who thought he was a rock climber--he somehow managed to get up on the counter by grabbing the handle of the oven door and clawing his way up the front of the stove(!) (Edit to clarify The stove was not in use at the time, and seldom is: I hate cooking: ) Believe it or not, this was cured by getting him a comfortable chair where he was high enough to sit and watch what I was doing on the kitchen counters. Naturally, the kitchen was gated off-limits when we weren't in there; But he had absolutely no interest in being in the kitchen unless we were.
@basenjifan I don't really consider b's (especially males) reliably housebroken for pee until almost 2 years--they're so excitable, developing control can take some that long.
That said, when was your boy neutered, when you got him? B4 you got him? I had a horrible time housebreaking a young male until I realized he had a bladder infection he caught from catheterization following his neuter surgery. I've also had dogs develop bladder infections from being cathetered to get urine samples. If his neuter surgery was within the past few months, or if the previous owner had trouble with housebreaking following neuter surgery, get him checked for a UTI.
Also, is your boy from a reliable breeder and do you have proof his parents weren't Fanconi affected?
Ok, dial it back a little, here: Are you aware that rescue staffers are VOLUNTEERS? People with full-time jobs, families, pets of their own plus foster dogs? These aren't corporations You're dealing with, they're non-profits! Don't you feel just a tiny bit self-absorbed and arrogant complaining, because that's the vibe I'm getting!
@tanza Yes, she could be. Then again, she could also be part basenji. The OP wasn't looking for your Holy Basenji-Breeder Annointment of her dog as a purebred! She merely asked if, based on her dog's appearance and behaviour, she might have basenji blood. Is your self-image as a basenji breeder so fragile that you have to shoot down every newbie who wants info? This is a basenji forum--I thought all basenji lovers were welcome. You, ma'am, are a basenji snob!
